$ cat A.pm
class A;

has $.a syntax error;
$ perl6 A.pm
===SORRY!===
Confused at line 1, near "class A;\n\n"

So, why line 1. Isn't the syntax error introduced on line 3?

$ cat A.pm
class A {
     has $.a syntax error;
}
$ perl6 A.pm
===SORRY!===
Unable to parse blockoid, couldn't find final '}' at line 2

We definitely have a '}' at line 3.

And finally,
$ perl6 --version
