Function arguments are available directly inside the annotation now.

Expand description

A struct to represent a weight which is a function of the input arguments. The given items have the following types:

WD: a raw Weight value or a closure that returns a Weight with the same argument list as the dispatched, wrapped in a tuple.
CD: a raw DispatchClass value or a closure that returns a DispatchClass with the same argument list as the dispatched, wrapped in a tuple.
PF: a Pays variant for whether this dispatch pays fee or not or a closure that returns a Pays variant with the same argument list as the dispatched, wrapped in a tuple.
