Comment (by tscrim):

 So GAP3 has `IsIdentical`, which was changed to `IsIdenticalObj` in
 GAP4b3. I think what we need to do is either:

 - a subclass of the GAP interpreter for backwards compatibility with GAP3
 which just has the one difference in `function_call()`,
 - check the GAP version in the `__init__` and set some private attribute
 which gets used in `function_call()`, or
 - store the GAP version as an attribute and use an `if` statement in
 `function_call()`.

 @aschilling For now you should be able to make that one line change
 mentioned above to `sage.interfaces.gap.function_call` (but I haven't
 tested it).
