in thread What's the best way to use Any YAML (not YAML::Any)

This particular distribution does depend upon non-CORE modules, but the YAML support is optional (which apparantly I haven't stated).

I don't think that requiring installation of a particular package when an adequate alternative is already installed is a satisfying solution. I haven't attempted to code such a requirement into Makefile.PL (or cpanfile) and see how the various CPAN clients handle it. I should probably do so.

The run-time code would still need to select amongst the installed packages, so the original question woould still be cogent.

I wonder if some sort of capabilities database would be of help here. Modules providing capabilities would be registered upon installation. At run time the database would be queried to determine which modules were available; if one hadn't been loaded, one would be.

[MidLifeXis]: We don't, at least in this case ;-)
[GotToBTru]: and it includes a reference number that I didnt recognize
[GotToBTru]: I had to dig into the code to find out where it came from .. and it makes no sense
[GotToBTru]: so I emailed my contact asking if we could just stop sending it .. I'm afraid she is going to ask "what is that anyway?"
[MidLifeXis]: heh.
[MidLifeXis]: Most likely it is a code that some undocumented system, hidden behind layers of IT, deep in the bowels of the building under the machine room floor, reads that code to keep a presence switch from going off. :-b
