Change-vl-compoundstmt

Mutate a compound statement.

General form:

(change-vl-compoundstmt x
                        [:stmts stmts]
                        [:exprs exprs]
                        [:ctrl ctrl]
                        [:vardecls vardecls]
                        [:paramdecls paramdecls])

This expands into a suitable call of change-vl-compoundstmt-core. It allows you to modify statements without paying much attention to the kind of statement being modified.

Note that change-vl-compoundstmt-core has an elaborate guard; e.g., you must provide the same number of statements and expressions, and only provide a :ctrl when there is one, etc.

Macro: change-vl-compoundstmt

(defmacro change-vl-compoundstmt (x &rest args)
 (change-vl-compoundstmt-fn
   x
   (std::da-changer-args-to-alist 'change-vl-compoundstmt
                                  args
                                  '(:stmts :exprs :ctrl
                                           :vardecls :paramdecls))))
