The code for conversion is still there, but no longer triggered by the
import alone.
Somehow, having "import numpi2ri" trigger a change in the behaviour of
the rest made me uncomfortable.
Except to have to do something like "numpy2ri.activate()" by the time
2.2.0 final is released. In the meanwhile there is the few lines of
given in my previous email.

Fulfilling the Lean Software Promise
Lean software platforms are now widely adopted and the benefits have been
