/**
 * All global definitions of triggers, functions and procedures are evaluated here.

 * This happens, cause a global "block" does not have a definied start and end token 
 * like a package specification or a package body.
 * Thats why every construct is handled like a new part of the global package.
 * To overcome this problem, I could use an infinity lookahead - which should solve the problem 
 * and slow down the whole parsing.
 * Another idea would be to lookahead the next tokens and decide wether they belong to a package definition or not.
 * Then I could decide to stay in this global parsing state. By now lookahead gives the parser a hint to
 * choose the correct way on a given base. So we can't negate it easily.
 * On the other hand I could also hold the global state in a global variable. 
 * But this does not seems the correct way to solve the problem, I think.
