how to get left hand side symbol in action

[r0ller]

Hi All,

Is it possible in *any* way to get the left hand side symbol in an action of a 
rule? Say, I have:

A : B C
{<!-- -->
    std:cout<<"left hand side symbol is:"<<???
};

I tried to find it out myself and googled a lot but didn't find anything:(

Best regards,
r0ller
