 * 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.

This Grammar (or JavaCC) has several bugs.

Currently (2021-02-26) it fails for things like
- dbms_lob.trim(...),
- scalar subqueries in the WHERE-clause,
- TREAT(object AS type),
just to name a few.

Running PMD over a code base of approx. 1100 DDL scripts
from a commercial product, the parser failed for 182 files.
About 10% of these parsing errors actually showed flaws in the code,
e.g. "\u2013" instead of "-", or utf-8 encoding instead of windows-1252
(which is the standard for the product's scripts).
Still, ~ 15% of perfectly valid DDL scripts could not be parsed by PMD.

Nevertheless it should be best practice to call PMD for _every_ DDL script.

See /docs/pages/languages/plsql.md for further explanations on how
to use PMD-EXCLUDE-BEGIN and PMD-EXCLUDE-END.
