Just create a function that return a string with those three

`";`
`string c = "` ~ c ~ `";`;

void main()

As usual in D the answer is simple.)
But sometimes string mixins aren't desired, it would be nice to
mixin the code, not strings.
That's what template mixins are for (although in your example
string mixins are better suited imho). You may want to have a
look at

or of course http://dlang.org/template-mixin.html
