One interesting point will be what *nix calls the /usr/bin thingie for Python<br>
4. It would seem weird to call it /usr/bin/python3 and symlink it to say<br>
/usr/bin/python4.0 but maybe that's the most practical solution. OTOH, by<br>
2023, Python 2 will at worst be in source-only security release mode, if not<br>
finally retired so maybe we can reclaim /usr/bin/python by then. Oh well, PEP<br>
394 will hash all that out I'm sure.<br></blockquote><div><br></div></div></div></div><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div>Maybe the criteria for switching to 4 would be that all traces of 2 are gone.<br></div></div></div></div><div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
One other potentially disruptive change would be when Python's Einstein, er<br>
David Beazley, finally cracks the nut of the GIL. Should that require a new<br>
