However, as we can see, the list of variables x has now disappeared. In fact, these variables are then implicitly determined as being all the free variables in F .

When we want that x represent only some, but not all, of these free variables, we cannot use this shorthand. A more special case is one where the expression F is exactly a single variable x, that is { x P . x }. As a shorthand, this can be written { x P }, which is very common in informally written mathematics. And then E { x P } becomes [x := E]P accor Data Matrix 2d barcode for None ding to the second one point rule of Section 9.4. 9.
