What's the difference between a for-loop with an if-statement in it and the comprehension above? Even syntactically, they are almost perfectly matched on tokens. Except with a comprehension, you immediately know that not only it consumes a sequence, but it also produces one (whereas a loop could really do anything).

See my other answer to a similar question above, but basically for-loops and comprehensions are different due to their "learn-ability" and "read-ability". For-loops are easy for novice programmers to understand and functionality is broken up line-by-line as the processor consumes instructions. Comprehensions are an expression, and do several things in a single line. Novice programmers don't understand them, and I do believe that even for expert developers, they are harder to read than an equivalent for-if loop.
