Hi,
Is anybody interested in stuff like this (e.g., it could be nice for
teaching a class about writing math proofs):
sage: f = propcalc.formula("a&((b|c)^a->c)<->b")
sage: g = propcalc.formula("boolean<->algebra")
sage: (f&~g).ifthen(f)
((a&((b|c)^a->c)<->b)&(~(boolean<->algebra)))->(a&((b|c)^a->c)<->b)
Because there is patch at trac #545 that's been in dire need of somebody
to referee it for a long time with lots of code like the above:
http://trac.sagemath.org/sage_trac/ticket/545
Volunteer(s) needed!
