Dear UseRs,
I declared a `$` method for a S4 class. Can I have ab automatic completion
for this operator in R? Lists and environment objects provide this feature
by default, but my object is an extension of "function" class which does not
have subseting defined. How to be?
Completion should be automatic if you define names() to return the valid names.

Hi,
Shouldn't this be delegated to a custom method. ie :
complete <- function( x, ... ){
UseMethod( "complete" )
}
complete.default <- function( x, ... ){
names( x )
}
or maybe the equivalent S4 incantation.
This would separate the completion from the names, and therefore give
more flexibility to class writers.
