Fair enough; I missed that a feature that I had never tried to use was in fact already implemented. I have generally stayed with the 5.8 feature set because I am a big fan of backwards compatibility. I had forgotten to check if that generalization had already been done; mea culpa on that.

I use open my $foo,... to open a file in a sub and open FOO,... for the same at top-level. Having not actually needed open our or open state, I did not know that those already exist.
