Bug 9523 – std.conv.to will no longer convert enums to themselves

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
