[Python-ideas] String interpolation for all literal strings

[Mike Miller]

Here I go again, just stumbled across this.

Apparently C# (an even more "appy" language) in the new version 6.0 went through 
this same discussion in the last year.  Here's what they came up with, and it is 
very close to the ideas talked about here:

     http://davefancher.com/2014/12/04/c-6-0-string-interpolation/
     https://msdn.microsoft.com/en-us/library/Dn961160.aspx

TL;DR - Interesting, they started with this syntax:

     WriteLine("My name is \{name}");

Then moved to this one:

     WriteLine($"My name is {name}");

I suppose to match C#'s @strings.  I think we're on the right track.
