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.
