Code:
// This works:
auto re = regex(`a`, "g");
string input = "abc";
auto r = replace(input, re, "($1)");
// This gives a compile error:
auto re = regex(`a`, "g");
char[] input;
auto r = replace(input, re, "($1)");
The reason is that when input is char[], replace expects the format string to
also be char[], but "($1)" is, by default, of type string. But this is
unreasonable, because the constness of the format string shouldn't be tied to
the constness of the target string!
(Yes, DMD's IFTI has some limitations, it should be able in infer char[]
instead of immutable(char)[], but regardless, there's no reason why the format
argument must be char[].)
