Pos-option-some

Make-pos-option-some

Basic constructor macro for pos-option-some structures.

Syntax

(make-pos-option-some [:val <val>])

This is the usual way to construct pos-option-some structures. It simply conses together a structure with the specified fields.

This macro generates a new pos-option-some structure from scratch. See also change-pos-option-some, which can "change" an existing structure, instead.
