According to STD.pm, empty parens aren't allowed -- the semicolons
are required. One can write an infinite loop as either
loop { ... }
or
loop (;;) { ... }
At present Rakudo understands the first form but not the second
(patches welcome -- mainly the grammar just needs to treat the
expressions as optional instead of required).
Thanks!
