I opt for 'no'. () should just group and \((((@array)))) is a sillily
written arrayref. If you want @array to flatten lazily for enreferencing
this should be \([EMAIL PROTECTED]) which works without parens as well: [EMAIL 
---and is one char shorter than \(@array). And of course there is eager
flattening enreferencing: [EMAIL PROTECTED]

BTW, I like the ubiquitous interpretation of prefix * as infinite arity
marker at call sites as above and in sig definitions.
$TSa.greeting := "HaloO"; # mind the echo!
