Alternate versions of fileTape and runDrive

[erantapaa]

This is an example of an alternate way to write the fileTape and runDrive functions which avoids the dummy respond Unit call in fileTape. You also might be able to remove the need for Unit in the TResp type.

Example usage:

example = runDrive' (fileTape' "some-path") driver

Thank you ! Why not making this version the real one ?

[erantapaa]

Ok - I've replaced the old versions of fileTape and runDrive with the new ones.

I'm a little confused by the type of the new runDrive - perhaps you can figure that out.

Sorry I was in vacations, I'll see what I can do here
