Re: Examining Members of a module at Compile Time

class Test {}

class TestChild: Test {}

class TestChildChild: TestChild {}

alias Alias(alias Symbol) = Symbol; // this does the trick

void main()
{
foreach (item; __traits(allMembers, mixin(__MODULE__)))
{
		alias sym = Alias!(__traits(getMember, mixin(__MODULE__), 
item));

static if (is(sym == class))

Thanks, that works. It's not a perfect solution, though. It will 
fail to fail if you pass it something beside a symbol, instead 
failing silently. But it works okay for my use case.
