OK! I've updated the code, tests and documentation and published as
1.3.
I second the vote for a Character predicate for this in the base -
it would replace longer code in 7 places in a current standard
image. I think the name should be #isWordConstituent, since
"identifier" generally implies the first character is not numeric.

I think \w should include underscore to match what seems to be the
expected behavior out there. Going a step further, perhaps a
Character
predicate named something like #isIdentifierConstituent to include $_
in addition to pure alphanumerics would be useful.
Cheers,

Betreff: Regex11
Datum: Mon, 15 Sep 2008 09:33:13 +0200
Dear Vassili Bykov,
as far as I can see you've written the Regex11 package and I think
I've
found a bug. The documentation states:
\w any word constituent character (same as [a-zA-Z0-9_])
but the actual implementation fails with underscores:
'_' matchesRegex: '\w' "evaluates to false"
'_' matchesRegex: '[a-zA-Z0-9_]' "evaluates to true"
Should the bug be fixed because we rely on the definition of \w or
is it
the better way to adjust the documentation in order not to break
existing
applications? How can I help?
