One caveat, wouldn't this require that the user cannot call any
routines in the library that uses a routine that
comes later in the library? I.e.,

pro f1,x
if (...) then f2,x
end
pro f2,x
if (...) then f1,x
end

(linked as f1.pro and f2.pro)

would work fine if the user first calls f2.
If the user calls f1 first, then initally IDL
doesn't compile f2. When the user does call f2,
then IDL will try to compile the file again and
give an error that the user is attempting to recompile
an active module (since it recompiles f1 as well).

I find that this kind of co-dependency among routines
is pretty common though not usually quite as obvious
as what you have above.
