Yes I realize that it would be redundant to add an explicit entry for
'Array String'. But the documentation needs to be clear more than it needs
to be minimal. In this particular case, because the behaviour has changed
since 5.10.0, I think an explicit note would be helpful.
Array String string equality [*]
[*] these cases have changed, see perl5120delta
Further, it's not clear how the '$a eq $b' in the 'Any Any' line applies
when the left hand side is not a scalar but an array; not $a but @a.
But I don't see that 'string equality' is the semantics?
% perl -E '@a = (1, 2, 3); $s = "@a"; say(@a ~~ $s)'
