If you don't define the type of a Scalar and don't assign to it you'll have
an undefined Any (the Parent class of all the other types). If you assign
Nil to it then you have the same effect.
You can make $x to be Nil by iether casting it : my Nil $x; or binding it
to Nil; my $x; $x := Nil;
Basically Nil is special, slippery and a bit hard to catch.
