That was awesome, thanks for explaining that for us. It makes a lot of sense the way you explain it, and I quickly got the idea that you can make some powerful expressions this way.
The smooth creation of lists is I think one of the most important language features higher level languages have over lower level languages like C.
Just this thing:
c::a$"\n"
That's all I needed to be convinced that modern languages should have similar view constructs. In ruby it'd be:
c = a.map.with_index{|a,i| a == "\n" ? i : nil }.reject{|i| i.nil? }
Quite a mouthful, mainly because Ruby lacks a neat way to do '$'. But doing the same thing in C would really be awkward, and likely not as efficient unless you have some fancy code for building enumerators in C.
