My goal is to have a parser that does not place new restrictions on
an ancient interface.  The first step would probably be to define a
clear syntax description.

Eventually this would be also more allowing for variations in white
space, so that "<name>=<value>" could also be written as "<name> =
<value>".  ....which in turn would allow for

	foo+ = bar
vs.
	foo += bar
.

Just my 2¢...

Best regards,

Wolfgang Denk
