We don't need to produce a warning for each instance. Just once would be enough. And maybe this warning should happen without $VERBOSE.

misc #10541: Remove shorthand string interpolation syntax
https://bugs.ruby-lang.org/issues/10541#change-50226

* Author: Daniel Morrison
* Status: Open
* Priority: Normal
* Assignee: Yukihiro Matsumoto
* Category: syntax
* Target version: current: 2.2.0
----------------------------------------
I would like to see the shorthand string interpolation syntax, "foo#@bar" deprecated and then removed in 3.0.

My reasons:

1. Most experienced Ruby developers I've talked to don't even know it exists.
2. It has been the cause of real problems. http://status.cloudamqp.com/incidents/vj62pnp62tj9

When a syntax is not widely known and has the potential for problems, I think it makes sense to deprecate and remove.
