Trying to figure out hash references and methods.
Why does the "print $exp" work in case1,
while in case2 it only prints the hash reference?
Is it that critical that the explain method is on a separate line?
Or why does the print statement enable the "$exp->explain"
to work, as in the last line?

#case1

my $exp = YAPE::Regex::Explain->new($regex)->explain;
print $exp; #this works

#case2
###############################################
my $exp = YAPE::Regex::Explain->new($regex);
$exp -> explain;
print $exp; # this just gives the HASHreference
print $exp->explain; #this works
