Mail::Box::FastScalar(3) User Contributed Perl Documentation Mail::Box::FastScalar(3)

Mail::Box::FastScalar - fast alternative to IO::Scalar

my $fh = Mail::Box::FastScalar->new;
$fh->open(\my $out);
my $fh = Mail::Box::FastScalar->new(\my $out);

Extremely fast IO::Scalar replacement - over 20x improvement in getline() and getlines() methods.

You cannot modify the original reference between calls unless you "$obj-"seek(1, 0)> to reset the object - VERY rare usage case.

$/ must be "undef" or string - "" and \scalar unimplemented
