So, is there a difference between "cpdef" and "cdef public"? I wasn't
aware of that.
But that's great, and naturally suggests a patch for coerce_binary.
While we are at it: Are similar solutions available for the
cached_method decorators?
Currently, it fails as follows:
sage: cython('''from sage.all import cached_method
cdef class C:
@cached_method
def f(self,x):
return x
''')
Traceback (most recent call last):
...
AttributeError: 'method_descriptor' object has no attribute
'func_defaults'
Namely, cached_method tries to obtain certain attributes common to
python functions from its argument. func_defaults is just one among
others.
Best regards,
Simon
