Add Scala-specific JI logic
---------------------------
Key: JRUBY-5342
URL: http://jira.codehaus.org/browse/JRUBY-5342
Project: JRuby
Issue Type: Improvement
Reporter: Charles Oliver Nutter
Assignee: Charles Oliver Nutter
Fix For: JRuby 1.6
David Pollack has started adding JRuby support to his "Lift" Scala-based web
framework. In order for it to support Scala objects well, he needs a few
patches so that JI will pick up that certain objects are Scala objects and
treat them appropriately.
I have pushed his patches thusfar to the "scala" branch. I think if they are
not too invasive, we should include them.
A few thoughts so far:
* It unconditionally binds "[]" as an alias for "apply" if it's available,
since Scala treats foo() as a call to foo.apply. I think we should probably do
this only for Scala objects.
* It adds logic to our reflective binding of *all* methods to replace any
Scala-mangled operator methods, which could slow down binding non-Scala methods.
* The Scala-specific logic had to be "sprinkled" around a bit. A refactoring of
JI logic might make it easier to add similar enhancements in the future without
one-off "sprinklings" of code.
