<+camelia> rakudo-jvm 68e094, rakudo-moar 68e094: OUTPUT«Cannot unbox a
                 type object␤  in block  at /tmp/tmpfile:1␤␤»
<+camelia> ..rakudo-parrot 68e094: ( no output )
< moritz> p: my num $alpha = Nil; say $alpha.perl
<+camelia> rakudo-parrot 68e094: OUTPUT«0e0␤»

I think that parrot is correct here; the knowledge that a variable is
natively typed (and its return value) is known at compile time, so I see
no good reason why this shouldn't work
