No walker defined for `DECLARE`?

[Ferada]

Looks like the test cases for the walker don't work? At least on CCL and ABCL:

Sorry, No walker for the special operater DECLARE defined.
   [Condition of type SIMPLE-ERROR]

[hraban]

Same on SBCL darwin x86

[bobbysmith007]

I don't have (and haven't had) a common lisp development environment for quite a while.

I am open to merging fixes. It has been quite a while since I have interacted with any of this.

#1
I see that there was a PR I missed that claimed to fix things for ABCL (from Jul 2020). I tried merging that PR after a review. Please let me know if this resolved your issue or if further fixes are needed.

I am happy to merge patches (when I see them).

Ferada - I appreciate your contribution and am sorry that I missed it when it happened

I am currently investigating whether the test suite ever worked in SBCL. I am fairly confident that it did, but the question remains: in which version?

I haven’t found any results yet. However, I wanted to make a note of this page, which provides results for historical versions:

Arnesi | CL Test Grid
https://cl-test-grid.common-lisp.dev/library/arnesi.html

[kisp]

Just noting that the defwalker handler for declare was removed in this commit: de9a7f1. I’m considering adding it back to see how it affects the test suite.
