If you try to use the overloaded subscript operator of a class
in python, it fails like this:
(gdb) py print(gdb.parse_and_eval('b')[5])
Traceback (most recent call last):
File "<string>", line 1, in <module>
gdb.error: Cannot subscript requested type.
Error while executing Python code.
This simply checks if such an operator exists, and calls it
instead, making this possible:
(gdb) py print(gdb.parse_and_eval('b')[5])
