FWIW: Strictly speaking it's possible, but I doubt it's a good idea:

goto $EXP

with $EXP = "label-name"

so

sub retn {
    goto $EXP
}

would do if you've set a global $EXP before.

Please note that you can't goto into a sub or a foreach loop, so returning there is not possible.

BUT in 99.9% of all cases there are far better solutions than that ...

... maybe you just need to try a continue block?
