Hi Andy,
Oh goody. I get to help someone for once!
"note" is the same thing as "say", but to the std error:
$ perl6 -e '$*ERR.say: "print to std err";'
print to std err
$ perl6 -e 'note "print to std err";'
print to std err
$ perl6 -e 'note "print to std err";' > /dev/null
print to std err
$ perl6 -e 'note "print ", "to ", "std err";' > /dev/null 2>&1
<nothing>
"2>&1" redirects STDERR to STDOUT. And, you put it "after"
the "/dev/null". It is a "bash" thing.

"\n". It means new line. Perl takes care of whether or
not that is a CR-LF or a LF depending on the OS involved.
example:
$ perl6 -e '$*ERR.print: "print to std err\n";'
print to std err
