Note the `()` before parameter list. This would make your member 
function a function template, for which attributes will be 
inferred by the compiler based on the calls you make in the 
function body.

Of course, making it a template like this makes it non-composable 
with that same type as you're only inspecting functions, so you 
wouldn't be able to do e.g. a Group!(Group!(A, 3), 4);
