possible GLib mottos:

"flexibility is inversely proportional to simplicity and ease of use"
"we'll give you enough rope to strangle yourself right well."

is this a bug or is it behaving as designed, but with an undesirable design?

array/hash references work perfectly fine in $data; although they are arguably
not as clean, it's directly analogous to what you'd do in C (e.g., pass a
structure pointer).

since the C-level stuff with the name input_add is deprecated, and you can't
exactly emulate it, don't put it in ... as input_add.

on the other hand, you can write a cleaner wrapper under a different name and
with a different, more suitable signature, and that would fall under the
category of "API extension".  there was a discussion on the list a bit ago
about what to do with API extensions and sugar; what ever came of that?


perhaps something like G::IO->add_watch_simple ?
