 This minimizes the call overhead. So @wrap typically is used to provide an optimized
 way to call certain GAP functions.

+If an argument is annotated as `::GapObj` (respectively `::GAP.Obj` or `::GapInt`),

 Another use case for this macro is to improve type stability of code calling into
 GAP, via the type annotations for the arguments and return value contained in the
