[bug][10.6.4] expansion macro rewrite fails -> workaround

[hartrock]

Tried after User Manual and Reference v.10.6.4:

Code Select Expand

sr@free:~/newLISP$ newlisp
newLISP v.10.6.4 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h

> (macro (double X) (+ X X))
(lambda-macro (X) (expand '(+ X X)))
> (define double (lambda-macro (X) (expand '(add X X))))

ERR: symbol is protected in function define : double

Good catch. And it happens on 10.6.[23] as well.

But it works with:

Code Select Expand

sr@free:~/newLISP$ newlisp
newLISP v.10.6.4 64-bit on Linux IPv4/6 UTF-8 libffi, options: newlisp -h

> (macro (double X) (+ X X))
(lambda-macro (X) (expand '(+ X X)))
>  (constant 'double (lambda-macro (X) (expand '(add X X))))
(lambda-macro (X) (expand '(add X X)))
> double
(lambda-macro (X) (expand '(add X X)))
>

So this seems to be a minor issue.



PS: Is this the best place for such reports? Is it OK, to delete this post after a fix?

In v10.6.4 the manual entry has been changed to constant.



Note, that changes to an expansion macro definition only affect future loaded code, not already read and expanded code.



Ps: don't delete bug posts.
