Okay, well... the main pieces of feedback I'd give on it then is to not change the behavior of the '!' modifier. That's bad BC. Rather, introduce a new modifier for checking if a parameter was passed. Secondly, make these two separate patches as the new modifier is a separate feature from the single-arg parameter parsing.
FWIW, there are a few examples of this being handled by defining the default value of the parameter to something non-sensical (such as a length of -1), then doing zpp with "|l!" would leave the default -1 alone when NULL is passed, and you can treat as "not passed". Granted this is a bit of a hack and won't work for all situations. Your approach is more comprehensive, just saying that for many cases it's not strictly needed. -Sara On Thu, Jul 19, 2012 at 2:33 PM, Nikita Popov <nikita....@gmail.com> wrote: > On Thu, Jul 19, 2012 at 11:23 PM, Sara Golemon <poll...@php.net> wrote: > > Then I'm not sure what problem you're trying to solve either. :/ > > This solves two problems: > > a) Integer parameters cannot currently be skipped using NULL.
