Hello,John,
As you said,
BEGIN blocks are compiled and run first before any code in main and they have
lexical scope because of the {} brackets.
and in his case:
>
> #!/usr/bin/perl -w
> use strict;
> print "b in main: $b";
> a();
> #----------------------
> BEGIN{
> our ($b);
> my ($fn) = @ARGV;
> $b = `cat $fn`;
>
> sub a {
> print "b in a: $b";
> }
> }
>
Then,are the statements of 'print "b in main: $b";a();' compiled before BEGIN
block?or whether the opposition is right?Thanks.
