[rules-users] matches operator

[Wolfgang Laun]

The second operand of matches is just another String expression, and
therefore it could be a string literal, a variable bound to a String field,
or a String expression.

For instance, this
  $f1: Foo( $id1: id )
  $f2: Foo( this != $f1, $id2: id matches ".*" + $id1 + ".*" )
is a test for $id2 being a substring of $id1.

Or you could do
  $f1: Foo( $id1: id )
  $f2: Foo( this != $f1, $id2: id matches ".*(" + $id1 + ")\\1.*" )
which tests - what?
