If you were allowed to say that, you should also be
able to say

    [x in numbers]

but this already has a meaning as an ordinary list
constructor.

Requiring the word 'for' to appear in an LC ensures
that there is never any ambiguity.

However, it might be possible to phrase it another
way, e.g.

   [x from numbers if x%2==1]
