Right Rich, Thanks. But that was a simplified reduction of real usage.
Typically the declare is found in a nested structure:
(describe "something"
(context "fooey"
(with bar 42) ; declare comes from this macro
(it "works"
(should= 42 @bar)))) ; here bar be unbound
I'll see if I can restructure Speclj to get all the Vars declared at the root
level. But I'd still like to know….
Is this defined behavior? Or am I jumping through hoops to avoid behavior that
doesn't belong?
