By putting floor/ceiling/round/sign/abs as a candidates for the setting I was really aiming more for "inline PIR" than a pure Perl 6 solution. We still need those functions to have signatures and (perhaps) participate in multidispatch, and that's easier if the function definitions are Perl 6 (with the function bodies being inline PIR or a mixture of Perl 6 and inline PIR).
