Tricky. I don't think you can do it without the eval. Unless the /ee option does the trick as ikegami suggests.

s/.../.../ee is short for s/.../eval .../e, so that "unless" is not an exception.

Your suggestion of re-interpolation sounds nice but is probably very tricky to implement.

It's not possible since interpolation involved executing arbitrary code. Maybe a limited form of interpolation? That would be possible and useful.
