Should we deprecate comma?

[Ola Fosheim Grøstad" <ola.fosheim.grostad+dlang at gmail.com>]

"Comma operators should be used sparingly. The most suitable uses 
are for constructs strongly related to each other, as in the for 
loop in reverse, and in macros where a multistep computation has 
to be single expression." (K&R).

Kill it… D solves the use cases with other means.
