Time by time I always discover new things and tweaks with Perl. This
time its the first time I come across the keyword "CORE".
It took me some time to understand GLOBs and even the perldoc perlref
was only moderately helpful.
Can someone tell me where to read more of CORE and possibly other
default packages(?) I seemed to miss?
BTW: where are the BEGIN() and END() functions documented?

Great! I loved it. Thanks.
JK> The more normal functions may be overwritten like this :

Here it's again. Whats "CORE", whats "GLOBAL"?
Where can I read something about it?
Thanks in advance!
Ciao
Uwe
