@Thomas:
(this is completely unrelated to the actual bug)
This particular code was "simplified" from a more complicated macro
-- where for the else clause, I want to capture the original value, so
it would be something like:
(silly obj
:dog dog-line
cat cat-line) ==>
(case (:tag obj)
:dog dog-line
(let [cat obj] cat-line ))
However, in "simplifying" the example, parts of the macro was
removed, and thus it appears that we have this dangling cat symbol.
