pdb unintentionally interpolates strings with convenience variables #112343
Description
Bug report
Bug description:
Python 3.12 introduced $-prefixed convenience variables to pdb (#103693).
It automatically replaces $-words in strings, which is undocumented. @nedbat suggests this is unintended behavior.
(Pdb) p '$in'
'__pdb_convenience_variables["in"]'
This totally breaks MongoDB queries inside pdb, as it makes frequent use of such strings.
CPython versions tested on:
3.12
Operating systems tested on:
Linux

PR #112380 made to fix this. We can't easily achieve this with pure regex so I simply switched to tokenize.
