Re: [Sooc-devel] Message handlers, interfaces

[Mike R. <mik...@gm...>]

It sounds like there are good reasons for Sooc to have interfaces that
can have partial or (maybe) complete default implementations, and
other good reasons for Sooc to have interfaces that forbid default
implementations.  Maybe it should allow both?

I haven't thought this through completely, but maybe there can be
something like s_iface and s_pure_iface.  Pure interfaces would forbid
any default implementations either by providing no means of connecting
handlers or by zeroing the whole iface at the end of its init
function.

Also, regardless of how interfaces end up working, I think it might be
nice to have a debugging mode at runtime.  It can be on or off.  When
it's on, each class will track where its messages are connected.  User
code could then do something like s_dbg_msg_connections (stream,
Class).  There could potentially be other debugging help when
debugging mode is on.  This message tracking will be non-trivial to
implement, though.
