And even when the principle is put into practice, it can easily lead to
spectacularly bad application. Speaking of Lisp, consider Scheme's
dismissal of iteration as unnecessary because recursion does the job, and
then the textbook chestnuts of how *not* to compute things like Fibonacci
numbers. (Using accumulators to jigger recursion into tail call position
is a non-trivial "idiom".)
More generally, squeezing the last smidgins of non-orthogonality out of a
language are usually not worth either the design effort or the cognitive
load on users ("Okay, there's only one way to do this, but what the $#@%%
is it??")
