I've got some weird juju during a DMD upgrade. The code I've posted below is representative of code that used to work for me to scrape for objects to bind with Binderoo when using package.d to make a folder a module. It has been working for a while. Now it doesn't.

And, weirdly, testing on godbolt with every compiler supported shows *it never should have worked*.

So. Using nothing but a module name as a string, what's the correct way to get all members when that module is a package.d implementation?

template Alias( alias A )
{
	alias Alias = A;
}

template ModuleFromName( string strModuleName )
{
	mixin( "import " ~ strModuleName ~ "; alias ModuleFromName = Alias!( " ~ strModuleName ~ " );" );
}

alias StdRegex = ModuleFromName!"std.regex";

pragma( msg, StdRegex.stringof );
pragma( msg, "std.regex members: " ~ __traits( allMembers, StdRegex ).stringof );

For now this is not possible because there was a bug with packages and `__traits(allMembers)`. You're lucky because it's been fixed two days ago,  see [1], but that still has to find its path to the stable branch.

By the way if Bindero relies on `__traits(allMembers)` on whole modules, I advice you to test this PR, as it may break you code.
