Interesting, thanks! I noticed after your reply that it's not possible to use Hash::AsObject with L in one-liners (which I hadn't tried, I think); I imagine because of dueling AUTOLOAD trickery.

$ perl -ML -wE 'my $h = Hash::AsObject->new( foo => "bar" ); say $h->f
+oo'

Can't locate foo.pm in @INC (you may need to install the foo module)

😞

I am usually under strictures(2) to catch typos, so it's not usually a feature I need in packages:

$ perl -MHash::AsObject -wE 'my $h = Hash::AsObject->new( foo => "bar"
+ ); say $h->f0o; say 42'

Use of uninitialized value in say at -e line 1.

42

$ perl -MHash::AsObject -Mstrictures=2,1 -wE 'my $h = Hash::AsObject->
+new( foo => "bar" ); say $h->f0o; say 42'
