Hmm, I've never really felt the need to work that way. Usually it's
functions I want, not classes; but if they're classes, then generally
they're just to add a couple of methods, or change the construction
args, so single inheritance is plenty. (I created a
MultiLineEntryField class as a thin wrapper around TextView, adding
get_text() and set_text() with the same signatures as GTK2.Entry()'s
methods of the same names. That wouldn't apply to anything else, so a
mixin wouldn't help much.) But sure. If you want mixins, go for it.
