The :: prefix looks like a typo that takes advantage of an sbcl undefined behavior that parses ::force-copy? as the keyword symbol :force-copy? This makes the code non-portable to a CL implementation that doesn't share the same undefined behavior.

Oh, thanks for this. Would you mine rebasing and making sure it still works, both on SBCL and whatever implementation you're using? I didn't see this until now and have pushed some enhancements. |
