NAME
selfvars - Provide $self and @args variables for OO programs
SYNOPSIS
package MyModule;
use selfvars;
# Write constructor as usual.
sub new {
return bless({}, shift);
}
# Use $self in place of $_[0].
sub foo {
$self->{foo};
}
# Use @args in place of @_[1..$#_].
sub set {
my ($foo, $bar) = @args;
$self->{foo} = $foo;
$self->{bar} = $bar;
}
DESCRIPTION
This moudles adds $self and @args keywords to your Perl OO module.
They are really just handy helpers to get rid of:
my $self = shift;
Behind the scenes, $self is simply tied to $_[0], and @args to
@_[1..$#_].
Note that they are variables, not barewords.
INTERFACE
$self
Return the current object.
@args
Return the argument list.
DEPENDENCIES
None.
