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 STDER
having two
my $name = "Sean Fritz";
my $name = "Sean W. Fritz"; #functions as the shown assignment statment,
just functions as an assignment statment (I believe) and dosen't alocate
any memory or destroy the previous variable. I could be very wrong on
that part though.
I do know that
my $a = $a; #refrences whatever was the scoped $a before
will refrence whatever $a was prior to you creating that global var. so
it shouldn't make a diffrence if you redefine it with extra 'my's.
