In Python I am used to immutable strings, so string methods like replace return a modified copy. D1 string functions are similar. I'd like D2 to be like Python here, but in practice an in-place replace procedure and a strongly-pure replace function that returns a modified copy are about equally clear :-) Yet, if you perform many in-place operations on strings you may get confused (it happened to me), such confusion is less common with functional-style string functions.
