help(code.parameters) broken on issue-1024 branch

[LourensVeen]

Describe the bug The command help(code.parameters) is supposed to show a generated docstring, but this crashes at least on the issue-1024-new-build-system branch:

In [12]: help(se.parameters)

CoreException: tried to get unknown parameter '__qualname__' for a 'SSE' object

I think I may have broken something here, I definitely did something with __qualname__ and __name__ to fix some broken tests.

• [x] check with main branch version to see if it also crashes
• [ ] fix

On the main branch, I get:

>>> from amuse.community.sse import Sse
>>> se = Sse()
>>> help(se.parameters)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

amuse.support.exceptions.CoreException: tried to get unknown parameter '__origin__' for a 'SSE' object

Different error, but still broken. So let's fix this separately.
