in thread Any improvement over the code possible??

If I write like this: -

say looks_like_number '2'

It should return false as I understand.. but its not printing anything

Neither in the case I give there a number 2

    OK. got it worked by using the below code: -

    use Scalar::Util 'looks_like_number'; my $result = looks_like_number('abc');

    Do we have to import functions like this only? Else I have to do it for every function I import??

      Different modules have different requirements, which are usually in the docs:
      By default Scalar::Util does not export any subroutines.

      So, for this module, you must import explicitly. See also perldoc -f use

        Thanks toolic for a valuable information.. :)
