OMeta2 minor bug

Hi,

I think there's a small problem with the semantic predicate of the range rule:

range :a :b =

anything:x ?[a <= x & x <= b] -> [x]

A pair of parenthesis fixes the problem:

range :a :b =

anything:x ?[a <= x & (x <= b)] -> [x]

Thanks,

Doug

Yup. It's been a known issue
(http://lists.squeak.org/pipermail/squeak-dev/2012-August/165622.html)
but it has not been pushed to the package.

Thanks, looks like I didn't notice when this was reported before.
I've fixed the package.
