Well, Python *already* has closures.  They're just more like the Java inner
class flavor than the Scheme flavor:  explicit importation of objects across
scope boundaries, instead of implicit importation of names across scope
boundaries.  Python's flavor is actually *nice* "in the large" because it
makes the boundary leaks explicit.  Ir's "in the small" that it sucks by
comparison.

An answer can only aspire to being but a pale reflection of the glory of the
question, so thank *you* for the opportunity to fall short once again
<wink>.
