Let Perl parse it for you. You can *eval* it.

use Data::Dumper;

sub ROW (@) { return [ @_ ]; }

sub MULTISET (&) { return [ sort { $a->[0] <=> $b->[0] } shift()-
() ];  }

# observe:
my $multi_set = eval <<END_EVAL1;
MULTISET{ROW(1     ,'  3667 ','WARREN    ','OH'),ROW(2     ,'
2948','SHAKER HTS','OH')}
END_EVAL1

Beware eval with unsanitized user inputs like
