They felt that way to me even in 5.0! Well, perhaps I wouldn't say
"kludges", but they were one of those things that I always had to
double-check in the manual if I was using them right, unlike most of
the rest of the standard library, which quickly becomes second-nature.
_ENV, on the other hand, felt like second-nature from day one.
