On 64-bit, it would be useful for, e.g. pack() and unpack(). I can indeed imagine some use cases for "optimized" math/ops in userland using unsigned integer (legacy or bigint). However I am not really convinced we should use them. Or if we do I would also like to have more (like c# f.e.) but it would b very tricky to use in php, due to its nature. > Thanks. > > -- > Andrea Faulds > http://ajf.me/
