I agree that allowing $@ in prerequisites would allow easy to read and easy to
write Makefiles, but the lack of that functionality does not mean that the
same build method for multiple targets needs to get split up to different
dependency lines. With a static pattern rule you can do the same on with a
single line:

cat date echo ls pwd rm sleep sync test : % : %.o
