Serhiy Storchaka <[email protected]> added the comment:
Having a side effect at import time is not good. It will interfere with
programs which just import pdb, but not use it.
There are two other options:
1. Import readline at top level, but call set_completer_delims() lazily.
2. Do not import readline at all. Call set_completer_delims() only if readline
is already imported (sys.modules.get('readline') is not None).
I prefer the latter one.
