I can provide a little background on why particular choices were made for
R6. Generally speaking, speed is a primary consideration in making
decisions about the design of R6. The basic structure of R6 classes is
actually not so different from reference classes: an R6 object is an
environment. But m
I understand Hadley's point; it's a consequence of the modification of the
environment of the ref. class methods.
Good point, but it seems we can make that an option (there are advantages to it
of code quality and ease of writing, when it works);
Let's discuss possibilities, off-list until thin

Here's a simple example:
library(scales)
library(methods)
MyRange <- setRefClass("MyRange", contains = "DiscreteRange")

Could of requests:
1) Is there any example or writeup on the difficulties of extending
reference classes across packages? Just so I can fully understand the
issues.
2) In what sorts of situations does the performance of reference
classes cause problems? Sure, it's an order of magnitude slower tha
