But I'd say that what now happens with your example in git is correct. Within exlag(), the user-function LRM() is masked by the series-name LRM; the function is ignored and the first lag of LRM is created.

If that's not what "you" (hypothetical function-writer) wanted, then don't use varnames() on series you got via a list; you can't be sure that these names won't collide with other stuff -- not only functions, but variables of type other than series that you have defined. That's the point of the "List.$i" syntax.

I guess if we wanted to get very nanny-ish about this we could figure out a way to make varnames() fail on series whose names you're not supposed to have access to inside a function.
