Expr-stmt

Change-expr-stmt

Modifying constructor for expr-stmt structures.

Syntax

(change-expr-stmt x 
                  [:stmt <stmt>])

This is an often useful alternative to make-expr-stmt.

We construct a new expr-stmt structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

  (std::change-aggregate 'expr-stmt
                         x args '((:stmt . expr-stmt->stmt))
                         'change-expr-stmt
                         'remake-expr-stmt))
