Parameter type hints while typing

[tgr]

It would be awesome to get parameter type hints (maybe even parameter documentation) when typing function arguments. The doc command can be used for this but it's a bit inconvenient. Tab completion could be hijacked for this nicely:

$foo->bar(<tab><tab>

could show the type and name of the parameter.

$foo->bar(x<tab><tab>

would work in the normal way, finding global methods / variables / whatever starting with x. This way, it would be impossible to use double-tab to get a list of all global functions, but that functionality is fairly useless anyway.

Would love type hints... especially for the standard library.

type in

preg_match(<tab> 

and see

preg_match($pattern, $subject, &$subpatterns = unknown, $flags = unknown, $offset = unknown)
