For a simple example I'd like "arity" (I'm unclear whether it belongs in
std.traits or std.functional). Sure, I could write
ParameterTypeTuple!fun.length, but that's quite a roundabout way to go
about it.

So here it is. A first very small patch to add arity to std.traits.
As you stated it could really go either in std.traits or std.functional.
I chose to keep it in std.traits because std.functional is more about
creating new functions of modifying existing ones whereas std.traits is
about deducing properties.
Great. You should know I'm on vacation with scant access to email.
