Simon Lydell 996a171a4e Fix #3778: Make for loops more consistent ...

The following two lines might seem equivalent:

    for n in [1, 2, 3] by  a then a = 4; n
    for n in [1, 2, 3] by +a then a = 4; n

But they used not to be, because `+a` was cached into a `ref`, while the plain
`a` wasn’t. Now even simple identifiers are cached, making the two lines
equivalent as expected.
