Tip: assign a value to a hash using a variable as a key

[ToddAndMargo]

Hi All,

This one about killed me to find!  The guys on the chat line
figured it out for me.  Apparently some tutorial is wrong on
this too, but I couldn't figure out which one they were
referring to.

When assigning a value to a hash using a variable as the key,
use {} instead of <>


perl6 -e ' my %x = ( "a" => "A", "b" => "x", "c" => "C" );
           my $y="b";
           %x{$y}="BB"; say %x;'

{a => A, b => BB, c => C}


Wow.  I never would have guessed that one!
