Not to be too picky, but I'd imagine the syntax would be this:

val template = s"""This is string ${_:Int}."""

In don't understand why it doesn't work, actually. It should expand to:

val template = new StringContext("""This is string""").s(_: Int)

Which is valid code.

PR for etapolation at scala/scala#2793 was closed because of jitters.

The thread suggests more could be done with names in a StringContext, so this is not a duplicate of #7715. cmp"$smaller is smaller than $bigger"(x,y) where the cmp does the obvious computation and makes the args available to the template by name, as it were from the context local to the StringContext.

That "etapolation" coinage might be the best I ever manage; except for the "intersobralator" used by implicitNotFound.

interesting. could be revived as a discussion on https://contributors.scala-lang.org

Leaving a pointer to this gist here as a reminder that we once more or less had what's being requested here.
