SYNOPSIS

any copy( any x )

ARGUMENTS

x The value to copy

DESCRIPTION

Create a deep copy of any value. Contrasting with assignment, which creates another reference, this function traverses the entire structure and creates a clone. Note that this function is not pure, as even called with the same input, it returns a different copy each time.

 a = [5,6,7];
 myFunction(a); // pass by shallow copy
 myFunction(copy(a)); // pass by deep copy

Copying a structure containing a foreign pointer (for example a database or file handle, or a piece of binary data) will copy the pointer but will not copy the contents of that pointer.
