 ## Medium-Term
 - Wishlist features:
-  - Array initializer lists:
-    - `word xyz[3] = {123, 456, 789}`
-  - String initializer:
-    - `byte qq[10] = "abcde"` - will also add null terminator to string
   - A way to pass string literals as subroutine arguments
   - Multidimensional arrays
     - 2D array is implemented as array of pointers to arrays of `word` or `byte`.
