Have a look at the examples in Developer/Examples/Ruby/MacRuby - there are

The way I get the JIT to preprocess your fib code is simply to call the method
once. For example I wrapped your code in a class (not that I am saying that it

then.
(for example)

I always assumed (with no direct evidence) that it was because in
Ruby, constants have to start with an uppercase letter, and so to
match various method signatures/types sent through BridgeSupport,
constant types must be passed as constant types.
