Getting the parameters and other attributes belonging to the function overload with the greatest number of arguments

[pineapple via Digitalmars-d-learn]

I'd like to find the overload of some function with the most 
parameters and (in this specific case) to get their identifiers 
using e.g. ParameterIdentifierTuple. There have also been cases 
where I'd have liked to iterate over the result of 
Parameters!func for each overload of that function. Can this be 
done, and if so how?
