This code compiles just fine normally:

import std.array;
import std.stdio;

void main()
{
    enum str = q{writeln("hellojoeworld");};
    mixin(replace(str, "joe", " "));
}


but if you compile with -unittest, you get this error

This is particularly annoying, because it makes it impossible to use replace on
strings at compile time to strip out newlines before mixing them in (to avoid
screwing up the line numbers).
