+# Currently open issues

+- [] Fill up symbol tables/environments/types.
+- [] Add symbol name checking (first pass should fill symbol names on global
+     scope so that we can use global functions/variables before they are inside
+     procedures even when those come first).
+- [] Add type checking.
+- [] Support output dot files for visualizing internal data structures with
+     `graphviz`
+- [] Use bump allocators to avoid a large number of `malloc` calls.
+- [] Free memory. Not important for now, since it will be cleaned up at exit.
+- [] Add structs.
+- [] Add arrays and darrays.
