Prev:	in? ( elt set -- ? )
Next:	cardinality ( set -- n )

Vocabulary
sets

Inputs

set

a set

Outputs

seq	a sequence

Word description
Creates a sequence with a single copy of each member of the set.

Each set type is expected to implement a method on this generic word.

Notes
This will preserve the ordering of unique elements when called on a sequence.
