Design a rule whose LHS always matches anything in the workspace and whose RHS always rewrites so as to leave the workspace unchanged. What happens when you test this rule?
Design a rule whose LHS will match
name
in the workspace but will not match
name@host
. Is this possible with just
$+
and
$*
?
What happens if you arrange rules in a different order? Try reversing the first two rules in our rule set 3.
