No. As long as it is a policy. If I get feedback, anything can
be changed.

Yes, maybe I'm beeing paranoid here. There are many ways in
which exceptions can be safely accepted.

The point here was just to avoid a complicated policy on callback
names. To see an example, check the C code in the botton of the
page below:
http://sqlite.org/quickstart.html
There's a corresponding file named '5minutes.hs' in the
distribution where a callback type is used. Maybe a different
policy on how to type and use callbacks could be done.

Sure. Thanks for your thoughts!
