    | | | 28796 [Dave@Pr gm t] That would give me the reflection information, but I'd lose the parse

28684 [Dave@Pr gm t] Thanks. I've uploaded 0.1.4 that includes your patch.
28687 [nobu.nokada@] I think it's better that t_dump() returns false unless dumped.

How do you do "character filtering" of a string using each_byte. II
28695 [olczyk@in er] There has been a trend I noticed in the last few years of the Usenet.

A byte-compiler?
28709 [gnuvince@ya ] Is what I heard true?  Will Ruby have a byte-compiler?  If so, I think
28710 [vruz@ww .d g] do you mean a Ruby-to-java-bytecode compiler ?
