Especially in this case when the feature has already once been left "unfinished". The benefit is zero for me, if when I need to hint a boolean and can only hint a scalar. In that case, I will still have to do the validating myself. I might as well leave the type hinting out all together, instead of waste resources for having first PHP check that it is a scalar and then my own code to check that it is a boolean. Actually, if I can only hint "scalar" in general, I am essentially telling the users of my API that they should be ready for two types of errors. That which occurs when the argument is not a scalar and that which occurs when it is not a boolean. One will be a PHP error and the second will be an exception. Would be easier on them if I do not use type hinting at all in that case. I say, do it properly or do not do it at all. Tomi Kaistila PHP Developer
