New submission from Robert <kxrobe...@gmail.com>:
When pyclbr.readmodule_ex() is traversing "import __main__" or another
module without __spec__, it dies completely
with "ValueError: __main__.__spec__ is None / is not set".
=> It should at least continue with the (big) rest
as the comment in _ModuleBrowser.visit_Import() says:
# If we can't find or parse the imported module,
# too bad -- don't die here.
And optionally fall back to using __file__ when present?
