Re: Why to wrap Perl classes inside a Perl script into blocks

[herveus]

Howdy!

You're on the right track. However, lexical variables' scope is delimited by the blocks. package does not make a new scope.

Consider:

{
    package Foo;
    my $foo;
}
{
    package Bar;
    my $foo; # new $foo not to be confused with one above
}

Versus:

package Foo;
my $foo;

package Bar;
my $foo; # my declaration masks previous one
