Strict Rakudo version of this Perl5 one-liner

[yary]

Once in a while, our sysadmin tweaks something on an upstream mail server,
and asks us a few days later if our spam rate has changed. I invariably
whip up a perl5 one liner like this to get a daily spam count from my "mh"
mail folder:

scan +spam|perl -naE '$d{$F[1]}++; END{say "$_: $d{$_}" for sort keys %d}'

"scan +spam" spits out one line per message in my spam folder, with the
date in field 1. I'm using perl in an awk-like way, and taking advantage of
non-strictness to use a global %d without declaring it.

What's a good concise "strict" Rakudo one-liner that works the same? In
particular, is there a Perl6 one-liner that works line-by-line (not
requiring reading all STDIN into memory) and doesn't require a variable
declaration?

bufs and utf8

[mt1957]

Hi,

I can not do the following;
my Buf $b = 'abc'.encode;
Type check failed in assignment to '$b'; expected 'Buf' but got 'utf8'

But I can do this;
my Buf $b = 'abc'.encode ~ Buf.new();
Buf:0x<61 62 63>

Does the concatenation convert utf8 into Buf? Will there be a problem 
when it is converted back to string
with decode. I've tested a few simple utf strings which seem to decode 
right.


Greetings
