There is no way to re-define the variable in perl. The $, @, and % all
have thier own seperate namespaces, and thus the definition
my $in;
my @in;#creates *both* a scalar and array
the best way is to
use warnings;#start of every program!
and it will give you a bit of ugly output to S
claration in same scope at C:\tmp\t.pl line 6.

Friends,
When we use strict pragma, is there a way to "prevent" redefining a
variable?
use strict;
my ($i) = 5;# $i defined
print ("Val of i = $i");
my ($i)

print ("Val of i = $i");
