““I’ve programmed in all kinds of languages, said the tough old hacker as he eased up to the bar, and it don’t matter which you use... This is nonsense, of course. There is a world of difference between, say, Fortran I and the latest version of Perl or for that matter between early versions of Perl and the latest version of Perl. But the tough old hacker may himself believe what he’s saying. It’s possible to write the same primitive Pascal-like programs in almost every language. If you only ever eat at McDonald’s, it will seem that food is much the same in every country.””
