 In C an array is more or less syntactic sugar for pointers. In Nimrod, arrays are much more strict and safe to use. They are pass-by-value (meaning they're copied at assignment). When passing an array to a proc in Nimrod, the argument is a read-only reference, meaning it can't be assigned to. Take the following example:
 
 **C:**
