So here is a general response:

1. There is no unity on what to expect from interpolated strings 
in the thread. That suggests that a library solution should be 
established first using D meta programming capabilities. Only 
when there is unity behind a library solution (and it is being 
used in practice) should it be considered as a candidate for 
syntactic sugar in the compiler.

2. What is missing in terms of metaprogramming capabilities to do 
this well as a library solution. That ought to be addressed 
before making any extension to the compiler.

3. How does adding non-critical features to the compiler impact 
the ability to move forward with critical features such as 
improved non-gc memory management. What should the priority of 
this feature be related to other more imporant features?

4. How does this feature impact the learnability of the language. 
Currently it seams that newbies become confused by language 
features (not only in D, but also in Rust and C++), so how can D 
improve on that situation? And how can the design of this feature 
contribute positively in that regard?
