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
To join strings there are several options
for printing your best bet is to send a comma seperated list, as that
will have fewer syscalls (as per llama book advice).
EX:
print "Hello", " World", $scalar_that_will_be_attached_to_end,
@array_that_will_be_flattened;
