Question

I have a module which looks like this:

package Test;
use strict;
use warnings;

sub hello {
    my $val = shift
    print "val = $val\n";
}

and in another module I insert this one like this:

my $module = 'Test'
eval "require $module";

How can I call the function hello in the second module /I mean like a function not like a method/.

You can use a symbolic reference:

{
    no strict 'refs';   # disable strictures for the enclosing block
    &{ $module . '::hello' };
}

Alternatively, you can export the function to the calling package (see Exporter):

package Test;
use Exporter 'import';
our @EXPORT = qw(hello);

sub hello {
...
}

Then in your code:

my $module = 'Test'
eval "use $module";
hello("test");
