concepts/Named-Tuples.md

+The [named tuples](./Named-Tuples.md) are basically literal linked lists.
+
+If you have a tuple like this:
+
+```
+(a,(b,(c)))
+```
+
+You can access the first element by just getting it. 
+You can access the first element by getting the second element and then the first element of that.
+And so on.
+
+It is probably not a coincidence that this is how the values of the named tuple are 3 long.
+
+```c
+SAC_ND_DECL__DATA( (SACp_pinl_271__emlr_220_i, (SCL, (NHD, (NUQ, (INT, (GLO, (NON, (NOT, (NDI, (INT, )))))))))), int, )
+```
+
+These named tuples were introduced to deal with the lack of macros with a variable number of arguments in C.
+The idea is that you can just make a macro with a single input and just unwrap the named tuple until you get what you want.
+
+The named tuples are build with the beautiful macros in `src/runtime/essentials_h/tuple.h`
+There T_* macros are defined.
