Re: [PhillyOnRails] Ruby in a JVM

[Cliff Moon <cliff@chariotsolutions.com>]

When I was at JavaOne last May there was talk of dynamically typed
language support in the JVM.  From what I understand, one of the biggest
problems (and an overriding reason why there are precious few
dynamically typed languages that generate Java bytecode) is that method
invocation in bytecode requires static typing.

JRuby doesn't have a compiler yet, but if you'd care to track the
progress of it or help out:
