canonicalizing values (like "interning" or "hash-consing").

Any value of comparable type may be canonicalized with the new
`Make[T]` function, which produces a reference to a canonical copy of
the value in the form of a `Handle[T]`.
Two `Handle[T]` are equal if and only if the values used to produce the
handles are equal, allowing programs to deduplicate values and reduce
their memory footprint.

As a special case, if the destination's core type is <code>[]byte</code>,
<code>copy</code> also accepts a source argument with core type
<a href="#Core_types"><code>bytestring</code></a>.
This form copies the bytes from the byte slice or string into the byte slice.
