Me too.  And supporting the "DESTROY as scope-end hack" also wrecks the
possibility of switching garbage collection paradigms. (how much mindshare
did the proposed "volatile" attribute get? Probably not a lot, since in the
absence of alternate GC methods everything is volatile anyway, rendering
C<:volatile> a no-op)

"Lexical" may be the wrong word then.  "Local" semantics are closer, for
when you want to set something that might not "leak out" but is /visible/
from do-file.

(several paragraphs thinking out loud about trying to change C<local> to use
aliasing instead of assignment removed)
