 - [ ] Fix invalid error message: AlmostLinearToSRGB :: (a: Color);; return {sqrtf(a.r), sqrtf(a.g), sqrtf(a.b), a.a}
 - [ ] Fix untyped literal going to codegen stage, example in arms_race
-- [ ] Fix and decide what to do when initializing global variable using not constants
+- [ ] Fix and decide what to do when initializing global variable using not constants C:/AProgramming/cparse/compiler/modules/Language.core:180:28: error: initializer element is not a compile-time constant
 - [ ] Fix adressing void is possible, maybe make it possible to address void
       using bytes

-- [ ] String declaration in Language.core
-- [ ] Way to import and force evaluate #import_lazy #import ?
 - [ ] Test and bulletproof any, slices
 - [ ] Need tests that make sure stuff errors out
 
-Memory:
+Future features
+
+- [ ] Add some directive that passes metadata arguments to compiler, stores them
+      in array and then those can be searched etc. Then we could add the link thing there
+- [ ] The ability for a type to also be a namespace seems like a good idea, a common pattern
+      emerges. Not sure how to execute it though without complications. Data for sure needs
+      to be nicely visible in a struct and those functions should be separate
+- [ ] Other kinds of casts, a cast from structs of same layout, a cast without conversion
+- [ ] Inject symbols into a declaration / namespace ??
+- [ ] Using directive to bring symbols into local scope
