The name indicates that it will remain the same despite changes to
`$ENV{PATH}`.

I'm not sure $^O is quite right for this, it has a lot of detail for unix like operating systems and not enough for windows. I think we want to know if it is unix, or win/vms/cyg/os9, and then we want something like win+powershell win+bash.

Maybe we can have opts for os and shell. I still don't think $^O is right for os as Windows9x and WindowsNT are both MSWin32 unfortunately. I'm not too enthused about inventing our own categories for os, but we may have to. Note #41 (review) and #42

I would like to delete from %opts and error if there is anything left over, that way we can add new options in the future, and if someone is trying to use those options on an older File::Which they will get an error.

I know this is a Windows environment variable, but I think we should use Env qw( @PATHEXT ) for this and other list type environment variables. This will make it easier to test windows behavior on non-windows OS. Any tests that test default behavior can also use Env.

Env is core as of Perl 5, so introducing it as a prereq shouldn't be a problem.

I guess this isn't related to this PR, but if PATHEXT isn't supported on Windows 9x or DOS, then we shouldn't use it on those platforms.

but we should at least consider that we may need to treat DOS/Windows9x as a different OS than WindowsNT.

I apologize for introducing this interface now. But we have to support it :(

Just a comment (you are already doing that).

I think this is the right approach.

When you are writing the documentation, you can assume that we will bump the version to 2.00 when we add the OO interface. OO examples should look like this: use File::Which 2.00;
my $which = File::Which->new; |
DRAFT: Start of OO interface.
This PR is just a placeholder. It still needs improvements to the tests, adding
the
os_shelloption (tentative name), documentation, and setting thePATH/PATHEXTas options.Connects to #40.
