Well, if youre working in a modular you might not want it recompiling
after every connection.

And you could have the eqivalent of interpreting where the blocks are run
like plugins, and only downcompiled when you tell it to (like in
SyncModular).

Right, but it wouldn't be able to downcompile commercial stuff, cos they
wouldn't make the source available.

Yes, its a significant win for blockless processing, less for for blocked,
but I expect its still worthwhile.
