Disclaimer: I have not watched the what C# did before writing 
this.

So I read the proposal for string interpolation in D, which I 
understand to be this one: https://github.com/John-Colvin/YAIDIP

The immediate thing that stroke me is the shell example. The 
proposed exemple is simply terrible code as it allows for shell 
injection.

One of the motivating example is SQL prepared statements, but 
once again, replacing this by the proposed string interpolation 
means SQL injection.

In its current form, I'm not convinced the current proposal is 
something we want. If this reaches any kind of scale, this will 
inevitably end up as a forbidden language construct in a linter.
