Since this is made as part of the conversion between dynbind and
lexbind, I'm generally worried about the risk that I removed an "unused
lexical var" which really was an "actually used dynamic var".
So, I prefer to keep the old var's code around, in case some problem
shows up that may point to a missing dynbinding of a var named FOO.

If you want to remove those, feel free, of course, but I have no plan to
remove them in the short term (nor to keep track of them so I'll make
sure I'll remove them in the longer term).
