Whoa! I'm not imposing religion on others. FAR FROM IT! Maybe the
examples I demonstrated were too tricky and missed the main point.
Right now, a sub would be written as:
sub mymethod {
my $this_is_my_name = shift;
@args = @_;
}
Under this RFC, you would write it as:
sub mymethod {
my $this_is_my_name = self;
@args = @_;
}
The key difference is this: $_[0] always contains the first method
argument, regardless of whether you're in an object-oriented or
function-oriented context. So, if you need to support both (like CGI.pm
and my own File::Remote must), you don't have to write some special
method that detects whether $_[0] is a valid class ref (see
self_or_default in CGI.pm).
Instead, you know that all the args are always in @_:
sub mymethod {
my $ME = self;
@args = @_;
}
And you can now call this as:
Class->mymethod
Class::mymethod
mymethod
And all will work without having to rewrite your sub.
This fixes a lot of stuff. Plus, "self" is one char shorter than
"shift"! ;-)
