I am real tired of Perl 5's stone age subs declarations. @_, oh brother.
In principle there is nothing wrong with @_ at least from the perspective that
it is quite useful to be able to have a single variable or keyword to
represent the entire argument list as a single value. Logically, a single
value is what an entire argument list is anyway, with individual arguments
being components of that. -- Darren Duncan
Except Perl 5 is a high level language and is suppose to be
more friendly to use. @_ is reminiscent of the difficulties
encountered with assembly code, especially having to work with
reference pointers to return array values. (I do love arrays of
hashes.)
Perl 6 fixes this big time! If for no other reason, this is why
I am migrating to Perl 6. I use "subs" to death. Totally
addicted to them and can't live without them . And, Perl 6 makes
it easy to understand values passed to subs at a glance. Not
to mention not having to waste time renaming $_[x] over to an
understandable name.
I think the important thing is having choice. Declaring parameters in terms of
named variables is normal and important, but when one does that it would still
be ideal to get a single extra variable that has all the arguments in it as
components, for when it is useful. -- Darren Duncan
