List comprehensions inside of a lambda print only `[` about python-uncompyle6 HOT 4 OPEN

This is a bug in the print action routines (probably uncompyle6/semantics/gencomp.py) that take the AST produced and format and print the results. You can see the trees that get created by adding the -T option to uncompyle6.

A like kind of thing that happens is that the wrong child of a node is looked at in the generation routine.

This works in decompyle3, so one fix would be to backport code from there here.

Are you up for fixing this bug?

Thanks for the comment, I had not seen decompyle3 before and it does seem to work there! I'll try switching to that repository as I am working on Python 3.8.

I'm personally not up to the task of fixing it, especially now that I have a clean workaround, but maybe a backport can happen one day indeed.

One of the problems when decompile in list Comprehension and result is :
parents = (lambda .0: [ Nodes.getParent(x) for x in .0 ])(nodes)
and In some cases, it outputs an empty file
In one case, a 60KB file became 120MB.had repeated
in python 3.7 and decompyle6

@mosadegh22 file a proper bug report in decompyle3 and I might investigate when I am able.
