All variables are global in nature unless you declare them in a lexical
scope.
$foo = "Hello Naveen";
if ( 1 ) {
my $x = 1;
}
In this example $foo is global, and $x is local to the if-block only.
And yes, -> is used quite often when you start using references or classes
(a module that acts like an object).

Subject: 2 questions
1) How do you define global & lexical variables in Perl?
2) Is the arrow (->) a commonly used Perl operator?
