I've been wondering why you can't do
c++ in Ruby. Finally I found this post by Matz explaining (in somewhat broken English).
I guess it make sense, given that in Ruby, variables are essentially just names or aliases for objects. So
c = 1; c++ would be the same as
1++. What would
1++ mean in any language? "Add 1 to 1, and assign the resulting value to 1"? Best you could do is have c++ return a new separate
2 object, which isn't what you'd expect if you come from a C-like background.
