Block

Make-block

Basic constructor macro for block structures.

Syntax

(make-block [:statements <statements>])

This is the usual way to construct block structures. It simply conses together a structure with the specified fields.

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

Definition

                       nil))
