Debugger behaviour - do you like the new 'smart command mode' feature?
The behaviour of the Python debugger changed a bit for 5.0. Previously, the debugger commands (such as 'c' for continue) would shadow Python variables with those names; so to show the variable c, you would have to type print(c).
The new 'smart command mode', from pdb++, prefers the variable names. So if a variable 'c' is defined, then entering 'c' in the debugger will show that value rather than continuing. Any command can be used explicitly with a prefix, e.g. '!!c'.
Some people have found this new behaviour awkward, and we're considering reverting it. Whether you like the new feature or not, please go and vote on this issue using the emoji on Github (thumbs up to go back to the old, thumbs down to keep 'smart command mode'):
