   By turning a string literal into a type we can create an interned string in C++. This has
   a number of useful properties, nuple is one of them. Read more [here][i].
 
+  There is a limit on string length of 10 characters (sort of arbitrary), you can increase it by 
+  editing the $(...) macro in the intern.h header. Or #define N3599 to use [N3599][]
+  proposal (adds string literal template to the language) which GCC and Clang implement as an 
+  extension, hopefully MSVC will support it too.
+
   Also you can check an online example [here at tio.run][i-tio] (or at [Ideone][i-ide]).
