Comment (by CaptainN):

 Another way to reduce validation boilerplate is to use a system like
 WP_OnceForm, which polyfills the missing values. OnceForm starts from the
 HTML form, so it knows up front which name/value pairs will need to be
 filled in.

 The php GPCS system is different, it just deals with whatever is sent to
 the server without referencing anything else, so if the scope will be
 limited in the same way as PHP's GPCS system, some query methods to check
 for missing items as MikeSchinkel described makes sense (they even make
 sense for dealing with the standard PHP superglobals).

 A comment on that implementation though - I'd prefer lower case function
 names (_get, _post, _request) to uppercase, because I think if these are
 lower case, it'll be less likely to be confused with the real superglobals
 at a glance.

 Maybe this is less of an issue, but I'd also like to see little else other
 than a wrapper around the actual superglobals. In other words, it should
 behave pretty much exactly as the PHP standard on which it's based. The
 headache with the current system (especially when you are first getting
 started) is that WordPress's model differs from PHP in a couple of
 substantial (magic-quotes), and some less substantial (the way the GPCS
 vars are mixed) ways, which causes a lot of problems before you find out
 what WordPress is doing in there, and here's a change to fix that.
