From an email from Larry Wall to the Perl 6 mailing list:
Reduce operators only turn infix into list operators. What you really
want here is a hyper-fatarrow:
my %h = @k »=>« @v;
No, i’m not going to post every single Larry Wall quote from his every email.
I just like the word “hyper-fatarrow”, which refers to the fat arrow (=>) inside those angle quotes (»«), which you probably don’t have on your keyboard. Larry is quite brave to introduce Unicode characters as operators in a general purpose programming language. So he’s allowed to give them funny names too.
