Prev:	intersect-all ( sets -- set/f )
Next:	fast-set ( set -- set' )

Vocabulary
sets

Inputs

set	a set
exemplar	a set

Outputs

set'

a set

Word description
If the conversion is defined for the exemplar, converts the set into a set of the exemplar's class. This is not guaranteed to create a new set, for example if the input set and exemplar are of the same class.

Set implementations may optionally implement a method on this generic word. The default implementation returns its input set.

Examples

USING: sets prettyprint ; { 1 2 3 } HS{ } set-like .
HS{ 1 2 3 }
