Firstly, thanks for the PR!
If I'm not mistaken, this means that 2.7 errors are never passed onwards. To get to this
try
some othertry
above must fail, thenerror
always has a value and theor
short circuits. Indeed this only ever prints the error for Python 3.6, because it's the last to fail before 2.7. So this moves the problem from 2.7 to 3.6, but I'm pretty sure this is not quite the optimal solution.The linked issue spoke of reparsing with the latest Python version available, and that idea had some agreement. That could be possible using
sys.version_info
and iffing the parser versions again.
