 ## Critical Bugs
 * The 'range' function is fully generic (for all 'a') but only compiles when 'a' is numeric type
-* After use:ing the Int and Float modules, this command crashes the REPL: (+ ?a ?b)
+* Go over all the Array functions and make sure they are memory safe
 
 ## Big Language Features
 * Generic data types (apart from Array, which already is)

 ## Language Design Considerations
 * What's the correct type of the variable in a set!-form, i.e. (set! &x value) or (set! x value)
-* The 'copy' function should probably be a special form, just like 'ref'?
 * Is some kind of interface/typeclass construct worthwhile?
 * How should passing primitive types (that do not care about being referenced) as ref:ed parameters be handled?
 * How to handle heap allocated values? Box type with reference count?

 * Stop evalutaion of forms after errors to avoid "Trying to refer to undefined symbol" error
 * Built in REPL history (without using rlwrap)
 * Preserve whitespace to allow saving forms back to disk
-* Refactorings at the REPL
-* Hide instances of templates/generic functions when printing the environment (by default)
-* Warnings about giving away values should be compiler errors and not Haskell trace:s
+* Refactorings at the REPL. Rename, extract function, add/remove parameter?
+* Hide instances of templates/generic functions when printing the environment (by default, allow it as a setting)
 * Somehow make it possible to enter ":t foo" at the REPL (can't be done now because each atom is evaluated separately)
 * Rename type variables from t0, t1, t2 to a, b, c, etc.
