Re^2: Use of uninitialised value... but it is defined ?!

clear and neat explication, as always AnomalousMonk

this kind of problems happened to me too some time (years?) ago until i realized the right order.


my $variable  = 'value';
-----------  ---------- 
| 1          | 3

BEGIN{ say $variable}
---------------------
| 2

As the OP reveals, the compiletime runtime order implication is not so easely intellegible from docs: maybe is worth to put a note in perlmod where BEGIN block is described (well i do not understand why it is here, anyway; a separtate tutorial about the phases of the Perl process would not be better?).

The OP can profits the read of some stuffs about the matter:

There are no rules, there are no thumbs..
Reinvent the wheel, then learn The Wheel; may be one day you reinvent one of THE WHEELS.
