I noticed this comment in the '99 Revenge of the Son of Lisp Machine paper:
"An early version of MrEd supported bundles of parameter values as first-class objects, called parameterizations. ... This generalization turns out to be nearly useless in practice ... Worse, parameterizations defeat the essential purpose of parameters for separating global state from thread-specific state." Of course, parameterizations are back. What was the change in thinking that led to bringing them back? Thanks, Dave
