SYNOPSIS
mixed deep_copy(mixed arg)
DESCRIPTION
Create a deep 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 truly copied, too.
For other values this function is a no-op.
If DYNAMIC_COST is defined, every nested mapping or array counts
towards the evaluation cost in both size and nesting depth.
EXAMPLES
mixed *a, *b;
a = ({ 1, ({ 21, 22 }) });
b = deep_copy(a);
a[0] = -1; a[1][0] = -21;
--> a is now ({ -1, ({ -21, 22 }) })
b is still ({ 1, ({ 21, 22 }) })
HISTORY
Introduced in LDMud 3.2.6.
LDMud 3.2.9 added the dynamic cost to the efun.
