For DSP applications, just a few simple extensions can make an incredible
difference in algorithm prototyping time.  I've already implemented my own
set of extensions (e.g. shift registers, fixed-point data types with
corresponding math operations, etc.) and have used them extensively for
(relatively) rapid prototyping of algorithms that eventually are implemented
in hardware.  A standardized extension (formal or informal) would be very
useful and would greatly reduce duplicate work.

Agreed.  An informal discussion group (for DSP applications, if no global
coordinating group exists) may be in order.  Assuming this hasn't already
started in one form or another, is there sufficient interest in an ad hoc
group on C++ extensions for DSP use?
