Hello!

"Thompson, David" <dthompson2@worcester.edu> skribis:

I very much agree with that.  I don=E2=80=99t think =E2=80=98--pure=E2=80=
=99 should be the
default, because there are valid use cases for that.

As for =E2=80=98--ad-hoc=E2=80=99: making it the default is technically eas=
y.  The
difficulty is to come up with a nice transition/deprecation mechanism so
that we don=E2=80=99t break everyone=E2=80=99s script overnight.

Ideas on how to achieve it are welcome!

Thanks,
Ludo=E2=80=99.
