Yeah, I'm looking into those possibilities, trying to find a 
nonintrusive way to introduce compiler pragmas that we could use for 
implementing parts of JRuby in Ruby code (or that others could use). For 
example, something like this (a bogus name...I don't want to reveal any 
pragmas yet):

def foo
   ____NO_FRAMING = true
end
