Yes but why?  What is specifically wrong with the example below
other than that it works not as expected exactly?  The user may
find eventually that using 'eval' does the trick but she does not
understand why it is necessary.

    define all_rule
    all :
            echo $$@
    endef

    $(all_rule)
