Hmm... in "simple terms" :-) i don't know if simplicity exists when
telling the difference between our,my,local but here goes:
our
---
* Is Global
* $ABC::DEF::ghi is identical to our $ghi when in package ABC::DEF
my/local
--------
* my is very tightly scoped
* my variables are _not available_ to _inner subroutines_
(NOTE: the phase _inner subroutines_ above, it is available
to inner "blocks" - just not inner subroutines)
* eg.
sub abc {
my $jjj = "hello world";
&def();
}
$jjj will not be available to the "def" subroutine
If you had had:
sub abc {
local $jjj = "hello world";
&def();
}
$jjj would have been available to all inner blocks and subroutines
including the "def" subroutine
