put those together and an idea crops up: allow more than just local lib files 
in that pragma, URL's come to mind but I'd think that some way to say a path 
is relative to the root of the current package (local, mapped or whatnot) 
might be every useful.


pragma(lib, "foo"); // as today
pragma(lib, "@foo"); // derived from package root, downloaded if needed, 
might need to ask user "y/n" for that.

(BTW: hard coding the extension looks like a bad idea to me.)
