Re^4: Scope, package, and 'my' variables

In my original question, yes, that makes sense. But in my clarifying question, in which there are braces around the code in package bbb, why doesn't that set up an independent version of $var which then should get picked up by do_b and thus print out "second time for var"?

Thanks

package bbb;
{
  use strict;
  use warnings 'all';
  my $var = 'second time for var';

  sub do_b {
    print "In 'bbb' var is set to '$var'\n";
  }
}

It does declare a new lexical `$var` over which `do_b` closes. However, you call the subroutine before the assignment occurs.	[reply] [d/l] [select]

The issue is that the assignment of $var within the block under bbb never happens before you call do_b. Don't think of a line like `my $x = somevalue;` as a declaration of a variable to be initialized before the program begins. Think of it as a statement that runs when the program gets to it.
