Comment (by vdelecroix):
Hi,
I would like to have a `verbose` or `message` option:
{{{
sage: designs.transversal_design(7,6,existence=True)
False
sage: designs.transversal_design(7,6,existence=True,message=True)
(False, "By the Bruck-Ryser-Chowla theorem, no projective plane of order 6
exists")
}}}
But it looks like we are implementing ourself the propagation of errors...
What do you think?
Vincent
