Hi,

Hello,

I wonder what idioms are available to loop through
the lines stored in a scalar variable. I guess I'm
looking for something analogous to these idioms
for files and arrays respectively:

while(<FH>) {
# do stuff
}

open FH, '<', \$scalar or die "Cannot open \$scalar $!";

while ( <FH> ) {
    # do stuff
    }

foreach (@array) {
# do stuff
}

for ( $scalar =~ /.*\n/g ) {
    # do stuff
    }
