Note that 'dd' is not part of Perl 6. It is a Rakudo enhancement. (I agree it should be documented, but some disagree..)
dd is describing the value, not the container. it is describing the value you've got in the container, not the container. You can use ".VAR" to check out the container instead of the value: my Real $x; # Make a box that can only hold something 'Real' $x = 3.14; # 3.14 is a Rat, which is also Real, so it will fit in the box. dd $x; # Rat $x = 3.14, a description of the value in the box. say $x.VAR.of; # (Real) -- The box can hold anything that is Real (which includes Rats) On Sun, Sep 16, 2018 at 10:20 PM ToddAndMargo <toddandma...@zoho.com> wrote: > >> On Sun, Sep 16, 2018 at 10:07 PM ToddAndMargo <toddandma...@zoho.com > >> <mailto:toddandma...@zoho.com>> wrote: > >> > >> On 09/16/2018 06:50 PM, Curt Tilmes wrote: > >> > Note that an object that is a Rat also does Real (see > >> > https://docs.perl6.org/type/Rat#Type_Graph) > >> > > >> > say Rat ~~ Real > >> > > >> > True > >> > > >> > Your're making a box that takes a Real, then putting a Rat (that > >> also does Real) into that box. > >> > > >> > It then says "yes, you've got a Rat in there". > >> > > >> > > >> > >> Why is it changing thing on the fly when I tell it not to? > >> I claim foul !!!!!!
