I think that the parser is dificult because you just need to look at how the language are defined, a pseudo-BNC notation, this is the think that makes me thing that the language has a complicated parser. >>Why primitives are hidden ?

This is something that IMHO is an error. >>Why are Strings arrays of integers ? aString[0] is an integer, yes, it's >>the way it is, but I would like to have String as an array of chars, and >>char if you want as a descendant of Integer (nice election because a >>Unicode String is and array of double chars i.e. integer), I don't know >>you, but for me aString[i].chr =='x' is somewhat unnatural, because it >>breaks the semantic of a String, so it's not intuitive for me. >> >> > >This was never intuitive for me either. > > Thanks, at least I'm not the only one >>Why is Ruby an interpreter ?

Just as an example, the closures are not objects, yes you can "objectify" a closure, but closures seems to be a patch to the language instead of an extension of it. >>There are more things that I see as strange in Ruby, but this is enought >>for now ..... >> >>Please if I've make any inaccuracy , don't be too rude with me, I'm >>still learning, and I've a loooong way before understand everyting.
