The if statement modifier is just another way to write a logical and statement:
$ perl -MO=Deparse -e' display_nothing() if $match_type eq q/none/ '
display_nothing() if $match_type eq 'none';
-e syntax OK
$ perl -MO=Deparse -e' $match_type eq q/none/ and display_nothing() '
display_nothing() if $match_type eq 'none';
-e syntax OK
$ perl -MO=Deparse -e' $match_type eq q/none/ && display_nothing() '
display_nothing() if $match_type eq 'none';
-e syntax OK
