Bug 20657 – is() expression can't deal with tuples?

alias XX = AliasSeq!(int, float); pragma(msg, is(XX == AliasSeq!(int, float))); // TRUE pragma(msg, is(XX == AliasSeq!(U, V), U, V)); // FALSE pragma(msg, is(XX == AliasSeq!(U), U...)); // FALSE Now it's clear why this is the case; inference like that won't apply to template instantiation arguments (but I reckon maybe it could?)... but is there some other way to do this? How do we determine if a thing is a tuple? I'm iterating `allMembers` of things, and trying to filter, but I can't work out how to detect if a symbol is a tuple so I can exclude it...
