How can I (is there a way to...) call a subroutine using a variable. For example, A user provides the name of a subroutine in a perl module, maybe as <STDIN>. The perl script has to run that subroutine. But of course, the name of that subroutine is stored in a scalar. 
package ECHO_MODULE;

use Exporter ();
@ISA = qw(Exporter);
@EXPORT = qw($say_hi $say_bye);

sub say_hi {print "hi\n";}

sub say_bye {print "bye\n"}

-----------------------
print "enter subroutine name: ";
$subname = <STDIN>;

$subname() ????
