 # Goals
 
-- Support only R7RS implementations
-  - Needs to have cond-expand and library support atleast (propably much more)
+- Support only R7RS implementations (for now)
 - Same interface on all implementations
   - Some things that are procedures on one implementation are macros on other,
   but they must behave the same
 
 # Non goals
 
-- To support all R7RS implementations
 - To have every possible FFI feature
 - Compiling of C code at any point
     - That is no stubs, no C code generated by the library and so on
