[Parrot] New comment on Episode 3: Squaak Details and First Steps.

and First Steps":

Ok, I have 2 grammars:

grammar test::Grammar is PCT::Grammar;

rule TOP {
<foo>*
[ $ || <panic: 'Syntax error'> ]
{*}
}

rule foo {
'hello'
{*}
}

and

grammar test::Grammar is PCT::Grammar;
rule TOP {
<expression>*
[ $ || <panic: 'Syntax error'> ]
{*}
}

rule expression {
'hello'
{*}
}

Both grammars are ok, when I run parrot test.pbc and enter hello, the
first grammar(with foo) accepts the input hello, the second one

../../parrot test.pbc
> hello
too few arguments passed (2) - 3 params expected

I have up to date Parrot from svn.
