Rather, the type hint holds the promise that the > validation has already happened somewhere else. That most good libraries already have the validation code is my point here. Either the variable has already been validated, so the type hint is not relevant. OR the data still needs validating in which case only 'string' is now usable? With any pre-processing now requiring a switch back to string ... this is where I'm having problems seeing how if someone switches a library to using strict type hinting internally that will not have an impact on using the same library as it is currently being used without type hinting. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
