heat death == bad   (geekin, quote)

"Inf is Perl 6's standard numerical infinity value, so a list that runs to Inf takes ... well ... forever to actually build. But writing 1..Inf is OK in Perl 6, since the elements of the resulting list are only ever computed on demand. Of course, if you were to print(1..Inf), you'd have plenty of time to go and get a cup of coffee. And even then (given the comparatively imminent heat death of the universe) that coffee would be really cold before the output was complete. So there will probably be a warning when you try to do that."
