Even with this change it still fails to fetch enums with UDAs. Here's the failing test case:

@safe pure nothrow @nogc unittest
{
    struct T
    {
        struct Tag {}
        @Tag enum MyEnumA;
        @Tag enum MyEnumB;
        @Tag enum MyEnumC;
    }
    alias components = getSymbolsByUDA!(T, T.Tag);
    static assert(components.length > 0);
}

Suggested change

	static if (isAliasSeq!member || (isType!member && !isAggregateType!member))
	static if (isAliasSeq!member || (isType!member && !isAggregateType!member && !is(member == enum)))

User-defined types include both aggregates and enums. Maybe we should add an isUserDefinedType template to help people avoid this mistake in the future.

@pbackus Thanks! Should be good now.

Checked unittest, and it's fine.
