SYNOPSIS
mixed copy (mixed arg)

DESCRIPTION
Create a shallow copy of <arg> and return it. For arrays and mappings
this means that a new array or mapping is created with copies of the
original content. Embedded arrays and mappings are copied by reference!

For other values this function is a no-op.

EXAMPLE
mixed *a, *b;

a = ({ 1, ({ 21, 22 }) });
b = copy(a);
a[0] = -1; a[1][0] = -21;
--> a is now ({ -1, ({ -21, 22 }) })
b is now ({ 1, ({ -21, 22 }) })

HISTORY
Introduced in LDMud 3.2.6.
