Correction: for any punctuation character x except '[' and '{', there exist global variables $x, @x and %x. Those variables are not necessarily magic, and their existence doesn't depend on the fact that $x does something useful. For example, none of $}, @} and %} are magic, yet they are all global variables.

    $[, @[ and %[ work (or at least they do in 5.18.0). If ${, @{ and %{ were to work, that would break dereferencing.

    package Cow { use Moo; has name => (is => 'lazy', default => sub { 'Mooington' }) } say Cow->new->name
