NAME
Data::Pointer::SCALAR - The SCALAR pointer type
SYNOPSIS
use Data::Pointer qw(ptr);
my $ptr = ptr( 'foo bar baz' );
print $ptr->plus(4)->deref, $/; # bar baz
$ptr->incr(4)->deref = 'quux';
print "yup", $/ if $ptr->deref eq 'foo quux'; # yup
DESCRIPTION
The SCALAR pointer type is implemented much like strings are in C, however the default behaviour is to point to a string
and not a char
.

*p *p = val
- incr([$num])
-
Increments the position of the pointer (default is 1)
p++
- decr([$num])
-
Decrements the position of the pointer (default is 1)
