The same place as other syntax descriptions: in the language reference

According to the documentation:

    […] the elements of the new container are those that would be
    produced by considering each of the for or if clauses a block,
    nesting from left to right, and evaluating the expression to produce
    an element each time the innermost block is reached.

Does that help? If not, please try re-phrasing the question.
