Bug 8380 – -unittest makes it so that std.replace doesn't work on enums

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 /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/array.d(1453): Error: template std.array.replace(E,R1,R2) if (isDynamicArray!(E[]) && isForwardRange!(R1) && isForwardRange!(R2) && (hasLength!(R2) || isSomeString!(R2))) forward reference to template replace(E,R1,R2) if (isDynamicArray!(E[]) && isForwardRange!(R1) && isForwardRange!(R2) && (hasLength!(R2) || isSomeString!(R2))) /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/array.d(1453): Error: template std.array.replace(E,R1,R2) if (isDynamicArray!(E[]) && isForwardRange!(R1) && isForwardRange!(R2) && (hasLength!(R2) || isSomeString!(R2))) cannot deduce template function from argument types !()(string,string,string) /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/algorithm.d(414): Error: inout on return means inout must be on a parameter as well for inout(uint)() /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/algorithm.d(479): Error: template instance std.algorithm.DummyRange!(cast(ReturnBy)0,cast(Length)0,cast(RangeType)2) error instantiating /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/algorithm.d(414): Error: inout on return means inout must be on a parameter as well for inout(uint)() /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/algorithm.d(480): Error: template instance std.algorithm.DummyRange!(cast(ReturnBy)0,cast(Length)0,cast(RangeType)3) error instantiating /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/algorithm.d(414): Error: inout on return means inout must be on a parameter as well for inout(uint)() /home/jmdavis/dmd2/linux/bin/../../src/phobos/std/algorithm.d(482): Error: template instance std.algorithm.DummyRange!(cast(ReturnBy)0,cast(Length)1,cast(RangeType)2) error instantiating 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).

Scratch this. Apparently some local changes I had caused this.
