Perl6 CRO - 2

In my first post about Perl6 and CRO I  mentioned I had problems take care of POST and GET messages at the same time.  The problem was a misspelled semi-colon

get -> 'greet', :%zname {   say %zname:  content 'text/plain',  'bye'; }

I wrote a colon instead of the correct semi-colon, you see it above say %zname: the result was

Cannot resolve caller say(Hash: DateTime); none of these signatures match:    (Mu $: *%_)  in block  at myfstserver.p6 line 26  in code  at /home/tooljn/.rakudobrew/moar-nom/install/share/perl6/site/sources/1DC86B9F9A31CA5BEE35765E177159BAEDB91AAA (Cro::HTTP::Router) line 79

It took me some four hours to figure this out. If the error message had been a more helpful

%zname: is uninitialized or %zname: does not exist ...

I had probably spotted the problem instantly.

Now  my CRO server works beautifully. CRO seems amazing so far, a hell lot of functionality stuffed in there. Now I only have to learn Perl6. The language is truly great and CRO looks even greater and it is only the first beta version, really looking forward to the next version.

Update:
I just learned the colon I tripped over is an alternative method invocation syntax, which makes my complaint invalid. I need to learn Perl6 before complaining, but thinking before talking is not one of my stong suits, (either😊)
