>Programmers familiar with the use of sigils to indicate variables intrinsically grok this phrase, but it looks like gobbledygook to non-programmers.

While I understand where you're coming from, I'd argue that programming-related concepts are all "gobbledygook to non-programmers", that's to be expected. Having something like (this is close to valid Raku but it's not)

    Positional[Any] ages = [42, 38, 25];

doesn't make it any easier than

    my @ages = [42, 38, 25];

unless you already have prior knowledge of arrays, assignments, types, etc.
