This would also conflict with one of the following:<br>
<br>
1. Allowing `$` for the Dollar library.<br>

<<a href="https://github.com/apple/swift-evolution/pull/354" rel="noreferrer" target="_blank">https://github.com/apple/swift-evolution/pull/354</a>><br>
<br>
2. Reserving `$` for the debugger.<br>
<br>
<<a href="https://github.com/apple/swift/pull/3004" rel="noreferrer" target="_blank">https://github.com/apple/swift/pull/3004</a>><br>
<br>
(The latter "test and merge" is failing for some reason).<br>
