kcott,

Thanks for your help.

Unfortunately, perlobj says the same thing as the camel book. But I was looking for a method in AUTOLOAD that exposed a remote API's interface -- kind of like the DYNALOAD linkage to dynamic libraries.

I realize now there is no linkage there at all. After looking more closely at the Business::PayPal::NVP package, I see that the API is actually reached via a url. Other than the magic of AUTOLOAD itself, there is no other magic happening.
