+/*
+ uncovered:
+
+ check_removal always returns false for Score contexts, it has been that way
+since I joined the project. There is a reason for this: The typeset score is
+stored in the Score_engraver, which in turn is accessed through the
+Global_context returned by ly:run-translator. So the score-translator must be
+connected to the score-context after run-translator finishes.
+
+I plan to change this: we should junk run-translator, and instead keep track
+of both context and translator in the SCM code, and access the typeset score
+directly via the created global-translator. Then it would be possible to
+disconnect score-translators at iteration time. -es
