This avoids a LOT of simple mistakes and REALLY hard to find program crashes. This is true of MS, Linux/Unix and the VMS program environment that I have used for about 40 years. I think you have to go back to maybe Windows 95 or RT-11 to not have that protection.
Modern languages extend this "protection" further, to the programmer model, with immutable bindings and data structures, shunning variables entirely.
