strict"; it also enables new features like the *say* verb, which (unlike
print) adds a newline for you. The implicit strictures feature was added in

That's the way I read this

Does it mean that:
use 5.12.0;

subroutine, without doing the assignment with every execution of the sub',
and without making the constant a global variable. by constant i mean a
variable which never changes value throughout the script
When you 'use strict', you must declare each variable using my().
my referrers = qw(one two three four);
When you do this, be sure to keep in mind that whatever variable you
declare will be scoped to the block it is in (or the file, if it is
declared outside of a block.

When I use the following portion of Perl code:
__
#!/usr/bin/perl
# use with:
# perl IfThenElse tfcfam (Use all of this at the command line!)
use strict;
use warnings;
print "Search by name: ";
my $name = ;
'egrep $name testing.
