When I first was shown programming (Fortran at school in the mid 70's) this aspect of fortran allowing variables to change their definition was the main "strange" thing about programming languages that all the books stressed. that programming languages had these strange imperative features because they were designed to be easily executed by machines rather than easily understood by humans.
A generation later and things have changed: machines are now more powerful and so programming languages using more natural declarative constructs are now feasible. Let the machine do the work and have the language more suitable for humans. But things are not so simple, it seems that in the intervening time humans have got used to the imperative machine-oriented languages and are now unsettled by human oriented declarative languages. You can't win....
