RE: [chuck-users] include

There were remnants and vestiges of an "auto-include" feature in Chuck sources last time I looked. These looked fairly promising. I'm not sure what the original intent was -- it didn't seem to be terribly functional in the last set of sources I looked at, but the general intention seemed like a good idea. As I read it, the intention was to look for a matching source file for undefined classes and load the matching source file on demand. The complication, presumably, is that the class implementations have to be loaded in multiple steps: parse all declarations of auto-included files first, and then bind references in a separate pass, in order to avoid problems with circular references. The code for the multi-step binding seems to be mostly there too -- more there, than the auto-include flag, anyway. The basic idea seemed sound, and is somewhat better than providing a lexical include facility.

Ah, I should take a look at that, then ... Is it a "simple lexical" include (like with the c preprocessor), or is it in a higher level, (what I'd like to call require/provide, like in elisp), so that the included code only needs to be compiled once?

Basically, I'd like "require foo" to check (in a hash table) if foo allready is provided, and in that case just return. If foo isn't provided, it could search the load path for "foo.ck", and compile that if found.

This would be very simple given a global namespace for functions and classes (so that the classes in foo is available for all shreds when foo is required in one). Otherwise require would also have to include the foo namespace into the current namespace.
