Typed or untyped

Problem

Declare two scalar variables side by side: an untyped $untyped and an Int-typed $typed. Dump both with dd while they are still empty, then assign 42 to each and dump both again. Look closely at how dd describes the two containers differently.

Example

The program prints (to standard error):

$untyped = Any
Int $typed = Int
$untyped = 42
Int $typed = 42
