Bug 9702 – std.string.replace for single chars too?

The first form is accepted but the second form is rejected: import std.string: replace; void main() { auto s1 = "hello".replace("h", "a"); // OK auto s2 = "hello".replace('h', 'a'); // error } DMD 2.063alpha gives: temp.d(4): Error: no overload matches for replace(E, R1, R2)(E[] subject, R1 from, R2 to) if (isDynamicArray!(E[]) && isForwardRange!(R1) && isForwardRange!(R2) && (hasLength!(R2) || isSomeString!(R2))) Maybe it's worth supporting the second form too. The advantage is possibly a little more efficient algorithm, and more flexibility.

You might like https://github.com/dlang/phobos/pull/5596 - it's "replace on steroids" (lazy, support for replacing subranges, Compile-Time overloads).

1) replace comes from std.array 2) This would be fixed by https://github.com/dlang/phobos/pull/6022
