Martin,
I think 'unparse' in FriCAS is badly broken. See for example:
(1) -> unparse((sin(x+1))::InputForm)
(1) "sin x+1"
Type: String
Besides it's use in Sage, do you agree that we should fix it anyway?
At the same time we should also remove the Fortranish names and any
other flaws we can find.
The only other alternative for _sage_ in axiom.py that I can see would
be to write something that interprets the S-expression output of
InputForm directly.
Regards,
Bill Page.
