Announce: Niecza Perl 6 v1
To mark one month since the first announcement of Niecza, to be known
retroactively as v0, this is another announcement, to be known as v1.
Further announcements will occur at intervals on the last Monday of
each month.
You have my assurance that the 'v1' tag, avai

Sorry.
TTIAR = Two Terms In A Row.
It's always a syntax error in Perl6, unlike Perl 5.
print, say, and sin as you've used them are not terms, actually. They're
expressions which happen to be function calls. You're calling .WHAT on their
return values. This is predictable going forward fro

One method-like thing that's come in handy for me as I've tinkered with the
language is .WHAT.
{ ... }.WHAT
Block()
AFAIK, you can use .WHAT on *any* term, because every term in Perl6 is an
object that is implemented by a class, and every class has a corresponding type
object (which is what .

That's very cool. Perl 6 is a functional language with lambdas and
everything.

Thanks!
Now the following code works:

I'm still having trouble with the other alternative:

Hello,
Looking at the first example in "Using Perl6", I have:
if $r1 > $r2 {
%matches{$p1}++;
} else {
%matches{$p2}++;
}
I was thinking that it should be possible to make this more compact, but the
two ideas I tried didn't work:
