 Features:
+ * :$ and :$$ to pop/return only single values
+ * allow top-level macros to influence the proces return code.
+   This can be used in macros to call $$ or ^C akin to exit(1).
+ * Special macro assignment command.
+   It could use the SciTECO parser for finding the end of the
+   macro definition which is more reliable than @^Uq{}.
+   Also this opens up new possibilities for optimizations.
+   Macros could be special QRegs that are not backed by a
+   Scintilla document but a normal string. This would immensely
+   speed up macro calls.
  * Numbers could be separate states instead of stack operating
    commands. The current behaviour has few benefits.

    This means that like the original BSD headers, implementations
    of the rbtree ops will be generated for every usage.
