Just noting that `${ \… }` exists already, although it's even more
confusing that `@{[ … ]}`:

    $ perl -E 'sub foo { say "wantarray: ", wantarray }  "${\foo}"'
    wantarray: 1

The `\` operator provides a list context to the function being called,
and the scalar dereference grabs the list in scalar context and return
the last element of it:

    $ perl -E 'sub foo { @a = 0..5 } say "${\foo}"'

So, yeah, we probably need something less ugly and less surprising.
