Hygienic macros (was: do...until wisdom needed...)

[Neil Hodgson]

   The right way forward for hygienic macros seems to me to be to do a proof
of concept implementation on top of standard Python so we can play with it
and find if there is anything that really needs it. If there are no strong
examples of benefits then the 'avoid extra rope' opinion will win. This
looks analogous to the ability to muck with Python's object/class model
which could have, but hasn't, resulted in unreadably weird code.

   do .. until is IMHO insufficiently better to justify hygienic macros.
