Or a new keyword?
begin with(ref a, in b) { ... }
It's syntactically unambiguous. I chose "with" because in a very loose
sense, it's a bit like Python's "with" block, which is to do with tying the
behaviour of a variable to a code block. Also "with" is vague enough that
it could be re-appropriated for other similar tasks - such as what "with"
actually does in Python (it's a very useful feature, which should be in
every language!)
