I'm in exactly the same situation; I'd thought for ages that the curly-brace
syntax was only valid for string offsets, so I use them in favour of square
brackets to avoid confusion.
I'd support reserving curly-braces for string offsets only (and vice-versa
for square brackets / arrays).
One awkward edge-case is where a class implements both __toString() and
ArrayAccess. It would be nice if you could distinguish which type of offset
you're accessing without casting.
