I agree. Make easy things easy, and hard things possible.

Similarly modules' formatting breaks if you set $/;
How many of the punctuation variables would be better with less-than-global
scope?

Or the function of $[ becomes per-array.
(What would be the syntax to read and set it? pos @array?
it seems to be syntactically legal but undef both as rval and lval)
If it's lexically scoped, would it be for arrays declared in that scope, or
for arrays accessed in that scope?
I'm not sure. I think I see potential breakage both ways.
