What would be a good approach? Store them in whatever case they come in, but
apply fc() when looking up keys?
If I dump all the vars with `set` I see all-uppercase, mixed-case, and
all-lowercase vars. Perl 5 seems to uppercase them all (when I dump %ENV with
Data::Dumper). And that naturally leads to what to do with stuff like 'ß',
which Perl 5 dumps out to me as `'▀' => '42',`

I'm thinking of just sticking a subclass of Hash to %*ENV on Windows, something
along the lines of
$ perl6 -e 'my %h := class :: is Hash { method AT-KEY ($k) { nextwith $k.fc
}; method ASSIGN-KEY ($k, $v) { nextwith $k.fc, $v } }.new; %h<Foo> = 42; dd
%h; dd %h<foo>'
{:foo(42)}
Int <element> = 42
