Hans-Martin,

I know it might sound defensive but do you *really* like the :+=
syntax?! To me this looks more like a regexp than an assignment ;-)

Unfortunately I don't remember having seen it. Could you repost the
changes?!

What could += possibly mean other than assignment?!

Well, the only uses I've seen sofar were inplace operations (and I wrote
'em ;-) Note that the ability to write binary selectors of this form
could be obtained by seeing if the left hand side is a variable (then,
the only requirement for the implementation would be that it returns
self) but it appears to me that it's a somewhat useless exercise...
