You can change/redefine a constant in Ruby though. You'll just get a warning to notify you about it.

Constants are variables that can't be changed.

constant variables are variables though. They just can not be changed once they are set but you can set them to anything. Thus they are a constant variable.
const x = 5 is a constant variable opposed to say the number 5, which is a literal constant.

@Pegasus: Only if you attempt to change them during runtime. Changing the value before runtime is perfectly valid.

Altering then might return an error too
