Backslash is always problematic since it's used as an escape.

I really like the &{...} idea, for the following reasons:

1. It's parallel in some sense to the &block notation, much as
* can be used on formal or actual parameters.

2. & is already a recognized operator (token).

3. There's no unary & in use yet except &block.

But maybe there is a good reason this should not be used?

Another note: I assume it would work with do/end also:

   myproc = & do blah; blah end

which I might even write as

   myproc = &do blah; blah end
