pyrepl is not in a good state

[voidus]

The pyrepl dependency seems to be not doing so well.

There is rarely any activity and the github and pypi versions have diverged: pypy/pyrepl#36

Additionally, there is python2-only syntax used:

> rg \\braise.\*,
pyrepl/pygame_keymap.py
93:                    raise KeySpecError, \
97:                    raise KeySpecError, "doubled \\C- (char %d of %s)"%(
103:                    raise KeySpecError, \
107:                    raise KeySpecError, "doubled \\M- (char %d of %s)"%(
122:                    raise KeySpecError, \
129:                    raise KeySpecError, \
135:                raise KeySpecError, \
164:                raise KeySpecError, \

pyrepl/python_reader.py
60:    raise cls, val, tb

pyrepl/pygame_console.py
302:        raise Exception, "erp!"

Not saying this to flame the people who worked on it of course, but it puts this package and its dependents in a precarious position. I'm using pdbpp in my daily work and haven't run into issues, so I assume the problematic code paths aren't used, but we should probably think if there is a way to support pyrepl or, if necessary, remove the dependency.

I understand that this might be a hard topic and hope we can find a good solution without explicit of implied shaming
