Even for an extremely simple instance of a reference class
x <- setRefClass("x")
y <- x$new()
calling the internal inspect function
.Internal(inspect(y))
produces enough output that it takes several minutes to print to the
console. (Actually I gave up and terminated the command after ~10
mins. It isn't clear whether the output would eventually complete.)
Are reference classes really so complicated inside, or is this a bug?
