no ticket yet for the hex problem

in the experimental branch ( that permit to start sage:

I just remove the alias. This is probably not a good solution.

See #24201 for the hex problem (experts help is needed)

comment:7 Changed 4 years ago by embray

Instead of the try/except and whatnot we could use six.get_unbound_method() for this. The name is a bit long but can be rebound to something shorter in the import statement.
