Pattern: Use of undesirable operator
Issue: -
It is typically a design mistake to use ::: in your code since the corresponding object has probably been kept internal for a good reason. Consider contacting the package maintainer if you feel the need to access the object for anything but mere inspection.
The good use of <<-/->> operator is in conjuction with lexical scope, where an environment stores state for a function or set of functions that modify the state by using superassignment. Otherwise it can become problematic as it modifies variables in the global environment.
