I think that adding new syntax for something that could just be a function is not a good idea at the best of times, but when it's such generic keyword that could be far more useful in other places (e.g. Linq style queries) it really needs to have a strong justification. The equation is not just "will PHP be better with this" instead it's "will PHP so much better that it justifies the known cost of adding syntax to the language, as well as the unknown cost of blocking future use of the 'in' keyword". I'm sorry, but I just can't see that the value in adding this comes anywhere close to justifying it's addition. cheers Dan
