Obviously C is not Perl.
I'm not asking for direction on this particular instance, which is why I stated my course of action with the current situation. (Though it will likely end up in some form as an XS extension at some point)
I'm asking for direction in general for contributing to OSS which has quite a bit to do with Perl. Granted in most situations, adding to someone else's work with Perl is simply a matter of using or inheriting so it often nicely sidesteps the issue.
There have often been times where I would have participated more in various capacities, if it didn't require so much effort to figure out how. Most people are more willing to help out if it's easy.
As I see it, this is a potential barrier to contribution. For instance, this is a bit different, but I think it illustrates my point well. There have been various things I've been wanting to contribute to CPAN for quite some time (years). One thing or another would hold them up. Trying to figure out how to install things in a nonstandard way, how to write tests for things like hardware. Examples were there wasn't a clear path on how to do it right. Then other more important things took precedence and they fell by the wayside (so far anyway).
For a community largely based of improving other people's work, it seems a fault that there isn't an obvious guide.
