Re: SV: C style assignment of variable values

Actually, that type of call is done quite a bit in other languages besides
C, you can do the same thing in VBasic and Delphi just to name 2. After
you see it a while, you get quite used to it and it becomes easy to understand.

It can get really complicated, though, when you get stuff like:

arr[proc(newarr[arrval(somefield.age[counter])])].somesub[counter]

and worst.
