in reply to IO::Scalar vs IO::String

If you need to use IO::Scalar in more than one place, and you want to keep IO::String in mind for later, you could wrap the call in a subroutine, and then if IO::Scalar is deprecated, or you just want to switch to IO::String, you can just change the one instance in your subroutine wrapper.

It adds the overhead of an extra subroutine call, but if I am relying on someone else's code, I have found it to be good practice to wrap it in my own method call so that later if the 3rd party code changes, I only have to change one place. The change can be to swap out the code for another 3rd party solution, or to write it myself.

    Hello hiseldl,

    Thanks for the suggestion - but I need this trick inside my own module, and just in one place, so the module itself can be considered the "wrapper" in a way.

    My consideration is which module to use right now, just hoping someone who has experience with both of them to give the right suggestion.

    This really would be a no-brainer if one of these modules was part of Perl's core distribution (or considered to become part of is for that matter).


      My recommendation is to use IO::Scalar because it is more mature and from the pod

        Note: as of version 2.x, these classes all work like their IO::Handle counterparts, so we have comparable functionality to IO::String.

      it has similar functionality to IO::String, so using IO::Scalar seems to be a win-win.
