Re: How to write this "properly" in Perl 6?

You can write a sub to return the next step: sub bondigi { state $n=1; return (, xx $n, xx $n++); } but I think an idiomatic Perl 6 solution would have a proper lazy Iterator. How do we write one of those?

uts and outputs of Temporal are UTC, then Perl is using UTC, not TAI. Is it TAI internally? Well if it's manipulating years, months, days, hours, and minutes as their TAI values, then yes, but if it's just working with an absolute count of atomic seconds, then there's no reason to say that it's TAI vs. UTC, because at that level, they completely agree with each other. -- Mark J.

a count of atomic seconds, great. That, however, is not TAI. UTC and TAI and the proposed leap-second-free UTC-replacement "TI" all tick at the same rate and at the same time, and you can devise any number of time scales that do likewise, differing only in the labels. -- Mark J. Reed
