In my image the second expression returns true as well.

In fact the '.' (dot) matches anything but the null character (see
RxMatcher>>#syntaxAny).

Thanks - I shouldn't make assumptions - it matches in Pharo but not in Gemstone - I assumed the implementations would be�identical.�

As you say the culprit is�RxMatcher>>#syntaxAny

In Pharo:

RxMatcher>>#syntaxAny

^RxmPredicate new

predicate: [:char | char asInteger ~= 0]

In Gemstone:

RxMatcher>>#syntaxAny

^RxmPredicate new

predicate: [:char | (Cr = char or: [Lf = char]) not]
