This module provides data manipulation functions, which at this time only
consists of \fBdeepCopy\fR and \fBdeepCmp\fR.

.PP
This function performs a deep and safe copy of arbitrary data structures,
checking for circular references along the way.  Hashes and lists are safely
duplicated while all other data types are just copied.  This means that any
embedded object references, etc., are identical in both the source and the
target, which is probably not what you want.
.PP
In short, this should only be used on pure hash/list/scalar value data
structures.  Both the source and the target data types must be of an identical
type.
.PP
This function returns the number of elements copied unless it runs into a
problem (such as a circular reference), in which case it returns a zero.

.Vb 3
\&    $rv = deepCmp($source, $target);
\&    $rv = deepCmp(@source, @target);
\&    $rv = deepCmp(%source, %target);
.Ve
.PP
This function performs a deep comparison of arbitrarily complex data
structures (i.e., hashes of lists of lists of scalars, etc.).  It returns true
if the values of the structures are identical, false otherwise.  Like the
\&\fBdeepCopy\fR function there are no provisions for evaluating objects beyond
what their values are when coerced as scalar types.
.PP
End sum, the same caveats that applied to \fBdeepCopy\fR apply here.
