"Arc, if I may, should be a language which is damn hard consistent at least on the basic concepts and which use kind of self generated strategy to reduce LOCs, not hard coded pseudo-concept like most languages."
You might be surprised to hear this, but many of us here like Arc for exactly this reason. It inherits its simplicity and conistency from Scheme.
However, Arc's main improvement upon Scheme is the fact that it uses some quirky abbreviations. These abbreviations do take the form of "hard coded pseudo-concepts."
I might have been wrong to inform you about these abbreviations when you were just starting to learn Arc. If you can, forget about (= ...) and (a:b ...) and stuff, and then see if you like the language any better. ;)
