According to S29, the parameter in sleep is named and therefore optional​:

] =item sleep
]
] our Num multi sleep ( Num $for = Inf )
]
] Attempt to sleep for up to C<$for> seconds. Implementations are obligated
] to support sub-second resolutions if that is at all possible.

But rakudo parsefails on encountering a 'sleep' without its parameter.

Fixed in r29769, but doesn't yet properly handle the 'Inf' case
because Parrot doesn't seem to have an 'infinite sleep' option
yet. So instead it's just sleeping for 68 years for now.

I'm leaving this ticket open until we can eliminate the hard-coded
constant.

Looks like current rakudo has sleep defined in the setting, and doesn't
have any constant at all, the parameter is currently required, not
optional.

I've now worked around the parrot limitation; closing without tests,
because we currently don't have the tools test infinite sleeping.
