Assigning `(try …)` to a variable name used for an exception may fail

[Kodiologist]

(setv e (try
  (/ 1 0)
  (except [e ZeroDivisionError]
    e)))
(print e)  ; NameError: name 'e' is not defined

This compiles to:

try:
    e = 1 / 0
except ZeroDivisionError as e:
    e = e
print(e)

We're trying to assign to an outer e in the except block, but that doesn't work, of course. We probably need a temporary variable for this.

@scauligi You may be interested in this, since it involves scoping.
