This compiled with 2.061

import std.conv;

enum E { a }

void main()
{
    auto month2 = to!E(E.a);
}

but does not compile with the current beta for 2.062. Rather, it gives the
error:

/home/jmdavis/dmd2/linux/bin/../../src/phobos/std/conv.d(274): Error: template
std.conv.toImpl matches more than one template declaration,
/home/jmdavis/dmd2/linux/bin/../../src/phobos/std/conv.d(330):toImpl(T, S)(S
value) if (isImplicitlyConvertible!(S, T) && !isEnumStrToStr!(S, T) &&
!isNullToStr!(S, T)) and
/home/jmdavis/dmd2/linux/bin/../../src/phobos/std/conv.d(1654):toImpl(T, S)(S
value) if (is(T == enum) && is(S : OriginalType!(T)) &&
!isFloatingPoint!(OriginalType!(T)) && !isSomeString!(OriginalType!(T)))
q.d(7): Error: template instance std.conv.to!(E).to!(E) error instantiating
