<masak> "Too few positionals passed; expected 1 to 0 arguments but got
0 in sub-signature" -- that's a somewhat LTA error message...
<vendethiel> :o)
<mauke> masak​: what triggers that signature error?
<masak> mauke​: something deep inside an errant execution. I didn't
bother to find out, exactly.
<masak> m​: sub foo([$head, *@​tail]) {}; foo([])
<camelia> rakudo-moar 315ec6​: OUTPUT«Too few positionals passed;
expected 1 to 0 arguments but got 0 in sub-signature [...]
<masak> ...but that seems to do it.

To be clear, it's less than awesome that the phrase "1 to 0" ever
shows up in this error message. 0 is indeed not in the range 1..0, but
only by virtue of that range being empty, not by virtue of the error
message making much sense.

<masak> m​: say 0 ~~ 1..0
<camelia> rakudo-moar 315ec6​: OUTPUT«False␤»
<masak> ;)
