   - call closure from not compiled context

-  First parse the expression, then simplify, then generate code.
-- At the vim9 script level: Allow using a function that is defined later.
-  Requires compiling functions only when the whole script has been sourced.

-  2. Compilation phase: compile :def function bodies, using declared types
-  3. Execution phase: Execute imports when encountered. (skip over functions)
+Forward declarations:
+  - Cleanup when sourcing a script again: all script-local variables, imports
+    and functions are deleted.
+  - make sure only constants in declarations are executed, no function calls.
+  - Declare a variable at script level without an assignment.
