Some mathematical functions and also some (not so) inert functions are implemented as objects.
For example, Perm is used to represent permutations.
p :=Perm([2,3,1,5,4]); # ==> disjoint cycles representation
Perm([[1, 2, 3], [4, 5]])
Perm acts as an inert function (like RootOf) but it's an object.
Is it possible to convert it into a true inert form such as PERM([[1, 2, 3], [4, 5]]) and so, being able to extract the arguments with op?
In this specific case we may use
[[1, 2, 3], [4, 5]]
but this is possible only because Perm has a convert export.
So, is it possible to obtain the arguments directly (without convert)?
This would be useful for other situations.
