I've started new branch called control_flow_fixes.
I've fixed the issue with RaiseStatNode. And unused variables that
were not assigned or referenced now you get correct message.
And I started to look inside sage problems.
Error compiling Cython file:
------------------------------------------------------------
...
# allow lambda functions
if self._nrows==0 or self._ncols==0:
return self.__copy__()
v = [z.derivative(var) for z in self.list()]
if R is None:
^
------------------------------------------------------------
sage/matrix/matrix_dense.pyx:451:13: local variable 'R' referenced
before assignment
I've looked into the sources and I think as cython is right here. 'R'
is allways NULL at that point.
