 - `goto` and `switch` fallthrough are not supported.
 - The address of (`&`) operator on local variables is not supported.
+- Arrays and structures cannot be stack-allocated or passed by value.
+- Function pointers and indirect calls.
 
 ## Known issues

 - All local variable declarations must be at the beginning of a function.
-- Aggregate types (arrays and structures) cannot be stack-allocated, passed by value or nested in a structure.
