I really don't understand why there should be a difference then between
delete and undef.  And if there's no difference, delete shouldn't be there.

I can't believe we need hash interfaces to arrays via keys, values, and each.

    foreach $item (0 .. $#array)
or 
    foreach $item (keys @array)


    foreach $item (@array)
or 
    foreach $item (values @array)

If we don't want to make a difference between arrays and hashes, let's
just choose one of them and boot it from the language completely?  I 
nominate arrays for obsolescence.
