SYNOPSIS
        mixed copy(mixed arg)

DESCRIPTION
        Create a shallow copy of  and return it. For arrays, mappings,
        structs and lightweight objects this means that a new array, mapping,
        struct resp. lightweight object is created with copies of the
        original content. Embedded arrays, mappings, structs or lightweight
        objects are copied by reference!

        For other values this function is a no-op.

        If a lightweight objects was copied, the H_CREATE_LWOBJECT_COPY hook
        will be called to finish initialization of the lightweight object.

EXAMPLES
        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.
