returns o if outcome is ok, otherwise return the outcome's own
error.

this switch as an equatable_switch

converts switch into a list of either a single element in case
switch.this.exists or `nil`otherwise

convert this switch to an option

convert this switch to an outcome

convert this switch to an outcome

converts switch to a string

dynamic_apply -- apply `f.call` to `Any.this`'s dynamic type and value

This can be used to perform operation on values depending on their dynamic
type.

Here is an example that takes a `Sequence Any` that may contain boxed values
of types `i32` and `f64`. We can now write a feature `get_f64` that extracts
these values converted to `f64` and build a function `sum` that sums them up
as follows:


NYI: IMPROVEMENT: #5892: If this is fixed, we could write

Get the dynamic type of this instance. For value instances `x`, this is
equal to `type_of x`, but for `x` with a `ref` type `x.dynamic_type` gives
the actual runtime type, while `type_of x` results in the static
compile-time type.

There is no dynamic type of a type instance since this would result in an
endless hierarchy of types. So for Type values, dynamic_type is redefined
to just return Type.type.

Does this switch contain a value of type A?

unwraps a switch that is known to contain a value

this can only be called in cases where it is known for sure that this switch
is not nil. A runtime error will be created otherwise.

unwrap value or get default

monadic operator

monadic operator to another monad

Apply f to elements of type A and wrap them in MB.

join operator

Does this switch contain a value of type A?

if this switch is nil return the result of f
otherwise just return this switch.

get A or cause an `exception T`

unwraps an switch if it exists, returns default value otherwise.

get A or panic with `B.as_string`

short-hand postfix operator for '!exists'

short-hand postfix operator for 'exists'

short-hand prefix operator for '!exists'

convenience prefix operator to create a string from a value.

This permits usage of `$` as a prefix operator in a similar way both
inside and outside of constant strings: $x and "$x" will produce the
same string.

value of a switch that is known to contain a value

This can only be called in cases where it is known for sure that this
switch is not a B. A runtime error will be created otherwise.

value of a switch or default if switch contains B

string representation of this type to be used for debugging.

result has the form "Type of '<name>'", but this might change in the future

There is no dynamic type of a type instance since this would result in an
endless hierarchy of types, so dynamic_type is redefined to just return
Type.type here.

equality implementation

result is only true if both x and y or
of choice type A and x.A = y.A

Is this type assignable to a type parameter with constraint `T`?

The result of this is a compile-time constant that can be used to specialize
code for a particular type.


it is most useful in conjunction with preconditions or `if` statements as in


or

name of this type, including type parameters, e.g. 'option (list i32)'.

convenience prefix operator to create a string from a value.

This permits usage of `$` as a prefix operator in a similar way both
inside and outside of constant strings: $x and "$x" will produce the
same string.

NYI: Redefinition allows the type feature to be distinguished from its normal counterpart, see #3913

return function

Get a type as a value.

This is a feature with the effect equivalent to Fuzion's `expr.type` call tail.
It is recommended to use `expr.type` and not `expr.type_value`.

`type_value` is here to show how this can be implemented and to illustrate the
difference to `dynamic_type`.
