I'm afraid I was a bit careless in the quoting. I am not implementing the
'dot operators' for numerical computation, I'm only implementing augmented
assignment (+=, >>= and friends.) But for what it's worth, I think the 'dot
operators' as using a dot are out -- there is no way the parser can
distingish between float-creation, attribute-lookup and matrix-operations,
and still remain as obvious as it is now. At least, I dont think so.  Using
another character would be possible, of course ;)
