NAME 
src/builtins/any-str.pir - Str-like functions and methods for Any
DESCRIPTION
This file implements the methods and functions of Any that are most closely associated with the Str class or role.
We place them here instead of src/classes/Any.pir to keep the size of that file down and to emphasize their generic,
"built-in" nature.
Methods
- chars()
- comb()
- Partial implementation for now, returns a list of strings (instead of a list of match objects).
- index()
- match()
- rindex()
- substr()
- trans()
- subst
- Replaces the first occurrence of a given substring or a regular expression match with some other substring.
- Partial implementation. The :g modifier on regexps doesn't work, for example.
Implementation of transliteration
our Str method Str::subst ( Any $string: Any $substring, Any $replacement )
our Str method Str::subst ( Any $string: Code $regexp, Any $replacement )
