no one is focusing on irrelevant detail -- everyone is focusing on the right answer, that is: "you shouldn't do that". kind of like: "How do I aim for my toe with a .38 revolver?" -- "you shouldn't do that, here is a pair of nail-trim scissors".

Comment on Re^4: Building a CPAN module with User Inputs
"Don't do that" is *not* the unitary "right" answer. There exist a range of circumstances
where it is appropriate and/or necessary to interact with the user during the installation
process in order to properly build the module. It may be that the input can be scripted
or put in a configuration file, but it's not always appropriate to insist that the user
create that from whole cloth up front.
Fortunately, answers that speak to the question have been offered.
