The last language from Alex's list to check out is Python.  I believe
a lambda in Python is fully transparent (but contains only an
expression), but perhaps someone with more familiarity can fact-check
me on that.

If I have that right, then all of the languages Alex suggests we check
for reference give "this" the same meaning as in the enclosing scope.
