Alternate string literal syntax (with mixins)?

[Kristian Kilpi]

String literals with mixins are a bit awkward sometimes (editor  
highlighting etc).

Some special marks -- I use @{ }@ here -- could be used to mark a part of  
a source file as a string literal, just like /* */ marks a part of code as  
a comment. For example:

   mixin(
     @{
       //this is a string literal block
       if(...) {
         ...
       }
     }@
   );

The @{ }@ marks have a close relation, of course, with quotation marks "".  
But because there is a starting mark and an ending mark, you can nest  
them. (And because they are used to mark a part of a file as a string  
literal, they are not actually the part of the 'working code' just like  
the "" literals are, if you get what I'm trying to say.)

E.g.

   alias @{
     str = @{ foo }@ ~ @{ bar }@;
     str ~= "blah";
     if(...) {
       ...
     }
   }@ MyCode;

    mixin(MyCode);
