+1. Nested functions should inherit constants from parent scopes, but not
+ local variables. At the moment the former works, but when trying to
+ (incorrectly) use a local variable from an outer scope in an inner
+ function, the compiler crashes:
+
+ foo :: () {
+ x := 42;
+ X :: 69;
+
+ bar :: () int { return x; } /* not fine; breaks */
+ baz :: () int { return X; } /* totally fine */
+ }
+
+ This is presumably due to the compiler maintaining a single tree of
+ scopes where a scope contains information for both constants and
+ variables. If this is indeed the cause, then there should most
+ probably be separate scope-trees; one which has scopes for constants,
+ and one which has scopes for variables.
