Reason why eval is difficult to understand is that there is no good
reason to have it, in the first place.

For example one can write:

   all_rule = all : ; echo $$@
   $(all_rule)

which expands the macro $(all_rule) and does parse the result as
makefile syntax.  That is everything said in the above statement,
just without 'eval'.
