 ## Nimrod Compiler
 #### Add support for full coroutines
-  * Full coroutines in contrast to Nimrod's closure iterators can capture the full call stack.
-  * Needs inline assembler to implement the stack switching.
-  * The GC needs to support conservative marking of multiple stacks
+
+**Description:**
+  * Many programming languages, in particular Lua, offer coroutines as way to provide light-weight collaborative tasking. Nimrod supports "closure iterators" which are comparable to Python's generators to accomplish the same. 
+  * However closure iterators are much more limited as they cannot capture the call stack completely.
+  * The best example to see the limitations of Nimrod's current way is that iterators cannot be recursive.   
+ 
+Here is a sketch of a possible implementation, but there are lots of other possibilities to implement full coroutines for Nimrod:
+
+  * Implement the necessary stack switching via inline assembler.
+  * The GC needs to support conservative marking of multiple stacks.
   * In particular the write barrier in the GC which does the 'isOnStack' check needs to be changed.
   * Using a bloom filter for quick testing whether an address belongs to some stack is likely to pay off.
   * Creating a coroutine needs to register a new stack to the GC.

 #### Implement a Nimrod backend for the Ragel state machine generator

+**Description:**
+  * Ragel is a widely used state machine generator which supports C, C++ etc. But not Nimrod. So let's change that.
