Test code:

import std.conv;
void main() 
{
    char[4] test = ['a', 'b', 'c', 'd'];
    string fail = to!string(test);
}

This fails with some template ambiguity (it seems):

/home/juanjux/sync/work/d/dmd2/src/phobos/std/conv.d(95): Error: template
std.conv.toImpl(T,S) if (!implicitlyConverts!(S,T) && isSomeString!(T) &&
isInputRange!(Unqual!(S)) && isSomeChar!(ElementType!(S))) toImpl(T,S) if
(!implicitlyConverts!(S,T) && isSomeString!(T) && isInputRange!(Unqual!(S)) &&
isSomeChar!(ElementType!(S))) matches more than one template declaration,
/home/juanjux/sync/work/d/dmd2/src/phobos/std/conv.d(110):toImpl(T,S) if
(!implicitlyConverts!(S,T) && isSomeString!(T) && isInputRange!(Unqual!(S)) &&
isSomeChar!(ElementType!(S))) and
/home/juanjux/sync/work/d/dmd2/src/phobos/std/conv.d(220):toImpl(T,S) if
(isStaticArray!(S))


Notice too how the error message is a nightmare - it doesn't specify the source
file where the failed "to!" is.
