See John Rose's post on this here: http://blogs.sun.com/jrose/entry/symbolic_freedom_in_the_vm We have implemented it in JRuby, and it works well. The down side is that Java backtraces can be a little hard to read when there's lots of symbolic identifiers. > A general solution would seem to be to use an annotation.

We generally use it only for binding methods written in Java to a Ruby name: @JRubyMethod(name = {"[]", "slice"}, reads = BACKREF, writes = BACKREF, compat = RUBY1_8) public IRubyObject op_aref(ThreadContext context, IRubyObject arg1, IRubyObject arg2) { Ruby runtime = context.getRuntime(); if (arg1 instanceof RubyRegexp) return subpat(runtime, context, (RubyRegexp)arg1, RubyNumeric.num2int(arg2)); return substr(runtime, RubyNumeric.num2int(arg1), RubyNumeric.num2int(arg2)); } - Charlie - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
