New description:
Some objects in GAP are not PList but does support indexation
{{{
gap> S := SymmetricGroup(5);;
gap> irr := Irr(S)[3];;
gap> irr[1];
5
}}}
or
{{{
gap> gens := GeneratorsOfGroup(SL(2,GF(5)));;
gap> m := gens[1];;
gap> m[1];
[ Z(5), 0*Z(5) ]
gap> m[2];
[ 0*Z(5), Z(5)^3 ]
}}}
We change the way gap lists are detected and hence more objects are now
wrapped as `GapElement_List`. In particular the examples above previously
failed inside Sage.
