Comment (by vbraun):
I'm still not particularly happy with the syntax. Especially handing
around tuples isn't really that userfriendly. I would propose the
following:
{{{
sage: H.<x,y,z> = HyperplaneArrangements(QQ)
}}}
as shortcut for
{{{
sage: H = HyperplaneArrangements(QQ, names='x, y, z')
sage: H.inject_variables()
}}}
and then construct hyperplanes as
{{{
sage: hyperplane = x + 2*y + 3*z - 4
}}}
and hyperplane arrangements as
{{{
sage: arrangement = (x + 2*y + 3*z - 4) and (y - 7) and (x + z)
sage: arrangement == x + 2*y + 3*z - 4 and y - 7 and x + z # brackets
are optional
True
}}}
If nobody objects then I'll work on that since I kind of need hyperplane
arrangements now...
