in reply to Changing -> to work within a string

Why not write a function that takes care of the concatenation? All the users have to do is call this function with as many parameters as they want, and it will return the concatenated string. 
my $directory = concat($machine->work_dir, "/subdir/", $machine->softw
+are_version, "/");

Or is this too difficult for the users to understand?

    my $directory = concat($machine->work_dir, "/subdir/", $machine->software_version, "/");

    That sounds an awful lot like perl's built in join function, called like so: 

    my $directory = join "", $machine->work_dir, "/subdir/", $machine->sof
+tware_version, "/";

      In fact, it is. I suggested writing a function that takes care of this because:

      1. you can alter the function in the future
      2. you can give it a more user-friendly name if wanted
