I think this will go a long way to addressing people's concerns when this came up previously. > The patch is available here: > http://ia.gd/patch/type_hint_53.txt I presume the idea is that some people (if they so chose) would want to type hint every parameter in their program. To facilitate this, I might suggest a "mixed" hint (like in the docs), and a null hint (though I'm not sure if it would be called "null" or "unset" or both). Finally, I don't want to ruin this, but last time there was disagreement over whether numbers should be coerced to the specified types, or left alone. What does your patch do? ie function x (int $x) { echo is_int ($x); } x ("5"); Thanks, Paul > It should be noted that this is not the first idea for type hints, that > credit goes to Hannes Magnusson who had posted a similar patch on the > internals list back in 2006.
