Idiom # 297: Sort a list of strings, case-insensitively

Code

In Fuzion collections are immutable by default, therefore in the following example the sorted list is assigned to a new filed, while the original list remains unmodified.

data1 := data.sort_by (s1, s2 -> s1.lower_case <= s2.lower_case)

2
data1 := data.sort_by (s1, s2 -> s1.lower_case <= s2.lower_case)
