I know I wanted to get the exit status of the program into a variable 
many times.
This would be possible:

ifeq ($(system test -e filename),0)
--FILE exists
else
--FILE does not exist
endif

Quite natural, isn't it? This makes it possible to easily avoid
most needs to call perl for this kind of stuff.

That stdout is not touched is just a byproduct then.

Another example: print date to stdout while makefile is evaluated:

dummy:=$(shell date)

Donnu. You are right here.
