Subject: [ruby-core:23364] Re: [Feature #1432] decrement and increment


Why is

  a+=1

less elegant than 

  ++a

However, I admit that using

  (x=a; a+=1; x)

to replace

  a++

is pretty evil looking.  (The postfix variants *are* a pain to emulate
correctly)

Are there other commonly used languages besides 'C' that support the ++ and
-- operators?
I always thought they were added to 'C' primarily to support efficient
pointer arithmetic --
something quite foreign to Ruby.
