Comment(by SimonKing):
Aha! Perhaps the problem arose like here:
{{{
sage: from sage.misc.misc import deprecated_function_alias
sage: print deprecated_function_alias(x.is_constant, "bla").__name__
None
}}}
And I think I have located the problem: [attachment:trac_10903_singular-
fixes.patch] introduces a change in `sage/misc/misc.py`, and apparently it
can happen that the lazy attribute `__name__` of `DeprecatedFunctionAlias`
returns None.
Perhaps it would be a solution to return `self.func.__name__`, if no name
can be determined by using `inspect.stack` and `gc.get_referrers`?
