[sage-combinat-devel] import statement strange behaviour

2012-05-18 Thread Frédéric Chapoton
Hello, trying to test my own files on sage 5.0, it seems that it takes many import statements. Some of them behave strangely : sage: import_statements(euler_phi) from sage.rings.arith import Number of positive integers <=n but relatively prime to n sage: import_statements(QQ) from sage.

Hi Anne, I also found the same behavior (I don't know why it worked before). Thanks Nicolas for identifying the real problem. That doctest failure with .nabla() would have been a mystery forever. -Mike On Friday, 18 May 2012 04:43:27 UTC-4, Anne Schilling wrote: > > Nicolas, thanks so much

Nicolas, thanks so much for figuring out where the problem is! I opened a ticket http://trac.sagemath.org/sage_trac/ticket/12969 For the record, this problem also occurs in plain sage-5.0 without the new symmetric function patch in the sage-combinat queue applied that Mike and I have been working
