First Steps:
srottak: You should check the action method definitions in the
action.pm file. Please note that each {*} indicates an invocation to an

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*

expression refers to the rule (or token) expression. If you declare a

Hello, is the word expression some kind of keyword or reserved word,
because the example works only after renaming rule expression to
something else (fe. the originally generated rule value {...} works) ?
