Test program:

----------------

import std.stdio;

enum A : bool { no, yes }

void main () {
    writeln(A.no);
}

----------------

This results in an error:

/usr/include/phobos/std/format.d(1599): Error: template
std.format.formatValue(Writer,T,Char) if (is(const(T) == const(void[])))
formatValue(Writer,T,Char) if (is(const(T) == const(void[]))) matches more than
one template declaration,
/usr/include/phobos/std/format.d(868):formatValue(Writer,T,Char) if (is(T ==
enum)) and /usr/include/phobos/std/format.d(1079):formatValue(Writer,T,Char) if
(is(T : bool))
