SafeList is a wrapper class for the normal R list. It should behave identically, except for the $ operator being overridden to require exact matches.
The constructor works identical to list(...) unless:
1) The only argument is a list, in which case the result is the same list, with its class attribute updated to include 'SafeList', or 2) The only argument is a SafeList, in which case that argument is returned unchanged
as.SafeList: Coerce an object to SafeList.
is.SafeList: Test if object is already a SafeList.
