Me thinks I am pushing "pointy" here!
#!/usr/bin/env perl6
sub Stooges() { return ( "Larry", "Curley", "Moe" ); }
my $x; my $y; my $z;
# ($x, $y, $z ) = Stooges;
Stooges -> $x, $y, $z;
say "$x $y $z";
$ Lambda.Test.pl6
===SORRY!=== Error while compiling /home/linuxutil/./Lambda.Test.pl6
Invalid typename 'say' in parameter declaration.

------> say⏏ "$x $y $z";
Am I missing something here, or did I just get a little
too creative for my own good?
Many thanks,

It's still reading the block signature (parameters and return type) that
it expects after the ->, until it sees the start of the block/closure.
Think of what follows it as a sub declaration without the sub name or
parentheses. A semicolon there says that what follows are optional
parameters, so it's expecting either a parameter name, or a type to give
to the following parameter name.
So it needs a {} to work with. Rats!
Thank you!
