It is returning 1 because it is in scalar context, @$ is undefined
(making the regex /(.+)/), and there is at least one character in
$test.  With the proper quoting of @ the $ will in fact cause problems
for the OP.  Here is an interesting fact: the strict pragma will not
catch @$ even though it is not a variable defined in perldoc perlvar
and was not declared.  This is why the strict pragma should always be
paired with the warnings pragma (and vice versa).
