The short version: This is intended to be the "cleaned up to check into the Parrot tree" version Dan mentioned, so now would be a good time to yell if you have problems with it. The documentation is much better (or at least larger) than that in the previous version. You _will_ run into bugs, but there's enough that works for it to be fun to play with.
The longer version: Additions: - statement guards: if, unless, while, until - loops: while, until - subs without explicit parameter lists get @_ (and do strange things with it, since flattening doesn't work yet). - hyped logical operators - more compiler tests. - more parser tests (John Kingsley). - more docs. - a bit more speed in the grammar by using regexes rather than a rule to hype operators - sub parameter lists will affect parsing (e.g. "sub foo($x)" will be a unary operator). Fixes: - || and && on lists return lists instead of scalars. - a few more misc. things - and a whole batch of fixes from Kingsley: - foreach $f (@a) {}" - "f() if (1)" - "next if $a < $b" - comment between end of block and next statement. /s
