But (I believe) an equivalent could be achieved by constructing a string
representation, and then calling gdb.parse_and_eval() on it [1].
However, I've been burned by doing so: in multi-threaded program
parse_and_eval (and I think inferior function call) resumes inferior,
and that causes no end of grief (including possible recursive entry back
into python, which triggers GDB assertions :-(
Tom, you may want to mention this gotcha when you expand parse_and_eval
documentation.
[1] parse_and_eval is not yet in mainline; the current patch for it is here:
