I think we're talking about two different things here. There was a
proposal to make -w -Mstrict the default, but that proposal did not say you
couldn't turn it off. I suggested just that as a build-time option for
sites that wanted it, but I haven't RFCed it and I doubt I will; I can't
see it being approved.

I don't use the environment variable (I think it's PERL5OPT without the S),
but I do run everything, yes, everything, with -w -Mstrict, with the
exception of most -e one-liners. If I used PERL5OPT then it would get in
the way of the one-liners. I've worked this way for at least three years.
I think we need the RFCs to be updated to make each position clear, then
wind up this religious issue. Here's my proposal for the RFC countering #16:
-w -Mstrict to be the default, for whatever values of warnings and
strictness make sense in P6. They'll be different by then, to be sure,
in ways I can't anticipate; but if they were the same as they are right
now, I would move for them to be the default. That at least enables the
spirit of the proposal to be captured.
-w -Mstrict not to be the default for -e. Obvious reason.
-w -Mstrict also not to be the default for a new flag, -z. This is so
people concerned about typing can put it on the #! line and get the
behavior they want at the expense of one to three characters. This part
sounds less elegant to me than I would like but it is very practical.
People who prefer pragmas can do no warnings; no strict.
