Re: [Bluemusic-users] Instrument Meta-Information

[Dave S. <da...@su...>]

Sorry I didn't notice this when you first published it, Steven, but I 
like this idea very much.  It would clearly make it possible for blue to 
have some very user-friendly features.  Also, if done in such a way that 
it could be incorporated into standard CSD files without breaking 
Csound's current parser, it could also be useful for other front-end 
programs; for example, we could use comments with a special syntax 
immediately following the initial ';' character.  It's a nice step 
towards moving Csound assembly language paradigm to something more 
modern and type-safe.

Although I don't have tons of free time, I would be more than willing to 
assist in the implementation of this feature.
