That 'x in seq' bit still shouts "containment" to me rather than iteration, though.

Perhaps repurposing 'from':

   (x from seq if f(x))

That rather breaks TOOWTDI though (since it is essentially new syntax for a for 
loop). And I have other hopes for the meaning of (x from ()). . .

Cheers,
Nick.
