plain application of X works​:

finanalyst​: rakudo​: for 1,2 X <a b> { say "$^x $^y" }
p6eval​: rakudo 34542f​: OUTPUT«1 a 1 b␤2 a 2 b␤»

multiple application does not​:

finanalyst​: rakudo​: for 1,2 X (<a b> X 'x') { say "$^x $^y" }
p6eval​: rakudo 34542f​: ( no output )
finanalyst​: moritz_​: am i missing something in the second range?
moritz_​: something's wrong
moritz_​: I guess it has to do with list flattening

<[Coke]> rakudo​: for 1,2 X (<a b> X 'x') { say "$^x $^y" }

I'm not sure if that output is correct, but it's definitely closer than the
original.

Yes, this is correct, just need tests to close the ticket.
