Senv

Change-senv

Modifying constructor for senv structures.

Syntax

(change-senv x 
             [:identifiers <identifiers>])

This is an often useful alternative to make-senv.

We construct a new senv 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.

Macro: change-senv

(defmacro change-senv (x &rest args)

                         x args
                         '((:identifiers . senv->identifiers))
                         'change-senv
                         'nil))
