I appreciate the time and effort Joe and Phil put into this, but I'm voting "no" because ... - Having an O(n) typehint does not feel like a good solution to me. People have argued that variadics are also O(n) so there's no real difference between the two. I disagree because no one in his or her right mind would pass 100,000 parameters to a function. This would not be at all uncommon for an array, though. IMO If you have to stop and consider the performance implications of the typehint or remember to only use the hint once then you've already severely limited its usefulness. - I don't see enough benefit *at this time* to be had from tying ourselves to this syntax. In my view there would need to be more benefit than eliminating the trivial foreach block you'd currently need to perform this check in userland. - I think it more sensible to spend time cleaning up existing bugs/functionality/idioms than bolting on superfluous new things here and there. Every syntax addition is a potential future BC problem, and while it may seem like a good idea now opinions can change and better ideas can arise. If you're shackled to a particular syntax it can make future improvements more painful. - I'm not sure that there's a strong consensus for generics at this point. Implementing a stopgap measure to simulate a watered-down subset of generics functionality feels premature to me. These are just my feelings after reading the relevant discussions. Thanks again for the work you guys put into this. Daniel
