AFAICT Guido has softened his stance on this somewhat. The main impediment to `map()` and friends at this point is the clunky `lambda` syntax. However here we see another benefit of syntactic comprehensions over higher-order functions: comprehensions can be inspected deeply and inlined or otherwise optimized as a special case, while a stack of higher-order functions might need a more advanced bytecode compiler or JIT to apply "deforesting" and inlining.
