Put that suggestion in the documentation somewhere, >and anyone who worries about the problem for five minutes more is crazy. I agree. This is the kind of crucial "design rationale" point that ought to be made very clear, both so that people will know when a system is well-designed (and choose to use it), and so that poeple will know how to solve straightforward problems straightforwardly. Too much documentation lacks this kind of "pearl of wisdom." I'd put the Scheme report in that category.
