I have two questions about GAP 4. First, is there a way to call a function
of known (but only at runtime) arity with a list of arguments? So given
FUNC and ARGS, where ARGS is a list, and FUNC is a function which expects
Length(ARGS) arguments. How to make the call?
My second question is probably philosophical. Which one is better?
Creating a representation derived from AttributeStoringRep and have some
fixed records, or simply use the AttributeStoringRep with Attributes?
