Working in more than one language, it's frustrating dealing with their differences. New Python learners chafe at the fact that Python names work differently than C variables. They want to know if function arguments are call by value or call by reference (neither). I saw a person on IRC once who was upset that Python lists were called lists instead of arrays.
Languages are different, that's why we have more than one of them. Language designers have to strike a balance between familiarity and innovation. We'd be pretty suprised by a language that used something other than "+" for adding numbers together, for example. Eventually though, the new language will diverge from the old, or what was the point?
This isn't to say that all languages are equal, there are better and worse, of course. But too often I hear people ranting about a language being stupid for some decision, without bothering to find out why it was done that way, and what benefit they might get from it.
To which, I say: WAT!?
