Map container.hash_map.HK, container.hash_map.V is
hash_map -- an immutable hash map from keys HK to values V
Functions
this hash map as a human readable string
example: [(0,a),(1,b),(2,c),(3,d)]
example: [(0,a),(1,b),(2,c),(3,d)]
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 hierachy of types. So for Type values, dynamic_type is redefined
to just return Type.type.

check if key k is present in the set of keys
get the value k is mapped to
get a list of all key/value pairs in this map
get a sequence of all keys in this map
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.

Type Features
empty -- convenience routine to create an empty instance of hash_map
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`.
