Macro Wb-Seq

Part of:

package fset
( wb-seq &rest args )
Constructs a wb-seq according to the supplied argument subforms. Each
argument subform can be an expression whose value is to appear in the sequence;
or a list of the form ($ expression), in which case the expression must
evaluate to a sequence, all of whose values appear in the result sequence. The
order of the result sequence reflects the order of the argument subforms.
