Ohh ... in Perl6 you can add a method call to things in the language. So
"hello world" can be "hello world".say() .... which got me wondering could
we do this to a list as well? ... and it turns out you can. This will work
too:
my $length = (@csv_fields.elems, @import_fields.elems).max;
Then I wondered what I was dealing with here:
say (@a, @b).WHAT;
Parcel() - a parcel?!!
And HOW it does the things that it does ...
Then I wondered what other methods you could put on the end of a Parcel ...
so I used ^ to get a handle on the metaclass to ask for its methods.
say (@a, @b).^.methods;
which came out like a stringified list of methods I could join up.
say (@a, @b).^.methods.join("\n"); # see output below
Lot's more to discover ...
Nigel, who is excited by opening up Perl6 parcels before XMAS! ;-)
