TimToady's comments on the matter: http://irclog.perlgeek.de/perl6-dev/2016-08-06#i_12976358 I stumbled on this while examining https://rt.perl.org/Ticket/Display.html?id=127341#ticket-history It seems this commit had a consequence that .Rat on an Inf or NaN does not actually return an object that can be stored in a Rat: https://github.com/rakudo/rakudo/commit/498d0a4ae4572a84f80c0c572632e12017d779f3 The issue is now there's no guarantee that a .Rat can be used as a Rat and thus the programmer has to perform additional checks. Here are some examples of the issue: <Zoffix> m: say ∞.Rat ~~ Rat <camelia> rakudo-moar 589061: OUTPUT«False» <Zoffix> m: Duration.new: NaN <camelia> rakudo-moar 589061: OUTPUT«Type check failed in assignment to $!tai; expected Rat but got Rational[Num,Int] (?) in block <unit> at <tmp> line 1» <Zoffix> m: Duration.new: ∞ <camelia> rakudo-moar 589061: OUTPUT«Type check failed in assignment to $!tai; expected Rat but got Rational[Num,Int] (?) in block <unit> at <tmp> line 1» <Zoffix> m: class { has Rat $.secret-ingredient; method new ($v) { self.bless: secret-ingredient => $v.Rat } }.new: ∞ <camelia> rakudo-moar 589061: OUTPUT«Type check failed in assignment to $!secret-ingredient; expected Rat but got Rational[Num,Int] (?) in method new at <tmp> line 1 in block <unit> at <tmp> line 1» <Zoffix> m: my Rat $x = ∞.Rat <camelia> rakudo-moar 589061: OUTPUT«Type check failed in assignment to $x; expected Rat but got Rational[Num,Int] (?) in block <unit> at <tmp> line 1» -- Cheers, ZZ | https://twitter.com/zoffix
