Feature request: String interpolation(like $"Greetings, {name}!" in C#)

[deerchao]

This is a feature that would make string formatting much more easier.

If it's not possible, how about a Format function: Format("Greetings, {0}", name)?

Thank you for this suggestion. I am happy to try and support the interpolation option, if that proves tricky then we can look to supporting Format instead.
