Peter is trying to communicate that some aspects of Python are
quite conservative, well-documented, and unlikely to change
across versions or implementations. The syntax of, let's say,
"def", is an example of such an aspect.
Peter has no particular evidence about the guarantees of the
sys._getframe(1).f_code.co_consts[0]
resolution; for all he or I know, the core Python maintainers
might change in an upcoming release the implementation of
co_consts. That's what I believe he intends you understand by
"brittle".
