Original bug ID: 4874
Reporter: vbigiani
Assigned to: @xavierleroy
Status: closed (set by @xavierleroy on 2012-03-24T14:01:03Z)
Resolution: fixed
Priority: normal
Severity: minor
Version: 3.11.1
Fixed in version: 3.12.0+dev

Bug description

The digits (0-9) match againt \b, as can be demonstrated by the following snippet:

let reg = Str.regexp "a\b";;
Str.string_match reg "a1" 0;;

which should return false, but instead returns true (because 1 is considered a word boundary).

Changed the notion of word constituent in Str so that they include digits 0-9 and the _ character in addition to letters. This is more consistent with other regexp packages (Perl, Python, egrep).
