Looks like this breaks the python bindings somehow. I don't think it should be too hard to fix.

 45/46 Test #45: PythonBindings .....................................................................***Failed    0.31 sec
      Start 46: test_fortran_interface

Can you run on gitlab as well just to make sure it doesn't break anything else?

• you'll need to add this to the docs list. using-eos.rst roughly round line 490
• python/module.cpp needs lambda attribute added
• test/python_bindings needs a correction to a test calculation by adding an addition | lambda to the test value

Thanks @jhp-lanl @dholladay00 should be fixed now. Tests running on re-git.

OK not sure why the python bindings are still failing... @rbberger any insight?

Maybe because lambda is a reserved keyword in Python?

Hmm... possible. I'll try do_lambda

[Yurlungur]

That worked! Thanks @rbberger !

Ok tests now all apss here. Checking on re-git as well. Ready for re-review, @dholladay00 @gopsub @jhp-lanl @rbberger

[Yurlungur]

Looks like tests are still failing on Roci due to a failed git clone. (@rbberger is this expected? Maybe related to the issues @dholladay00 reported on the mattermost?) However, everything else is passing. I think it's safe to review this and merge it now.

Looks good to me
