This is a significant tangent from this conversation. Does anyone think it would be possible/useful to create an event-loop library completely independent of the GUI library, but that the GUI library would use. I think there are probably vast uses other than GUI apps that could take advantage of such a component. Obviously the signal library could be put to good use in such an event library (once the performance optimizations are implemented).
This is pretty much just a random thought :)
I agree. I'd like to see the form validation broken out, for example, into a validation library, that could be used to validate db inserts, remote form submissions, etc. I'm sure that some of the magic that goes into a vector graphics library could be applied to sundry problem domains. Again, flatter heirarchy. -- Alan Gutierrez - alan@engrm.com
