in thread A sub named ∃

all my concious life any unicode-capable perl matches with \w any unicode letter, and I often match russian letters e.g. 0x0432 with \w.

I never did [[:alpha:]], but did succeeded russian letters matching with \w

    \w is [_\p{IsAlpha}\p{IsNumeric].

      Or, more concisely, [^\W\d]; so identifiers match /\b[^\W\d]\w*\b/. Gosh, I love that trick. :)

      - tye        

        I wish I'd thought of that.

      Oh, I see. we were speaking oranges and green oranges...

      Still, my first sentence is valid (∃!~/\w/), but you're saying that's not enough for identifiers rule... but I was not intended to say that I am rediscovering identifier regexp!
