Bug report

Bug description:

Python 3.12 introduced $-prefixed convenience variables to pdb (#103693).

It automatically replaces $-words in strings, which is undocumented. Conversations with @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
