3.0.1a6: innetgroup() not supported

Mark,

Thanks for working on a netgroup function.  Unfortunately, 3.0.1a6 seems 
not to have picked that up?

classes:

     "EXPORT_NFS"
         and => { innetgroup("nfs"), any };

...

# cf-promises -f ./test-innetgroup.cf
cf3:./test-innetgroup.cf:12,34: Unknown built-in function innetgroup(), 
near token '}'

Also, is there a more elegant solution than this dummy compounding to 
define my class?  I don't see it in the docs - all the examples I've come 
across have involved negation or boolean operators.  What's the proper cf3 
translation of, simply, "EXPORT_NFS = ( +nfs )"?
