+  # able to find it (due to a  bug).
+  #
+  # However, we don't know what conversions we may need to do a runtime. So we load up a
+  # text file which contains a pre-generated list of all the possible conversions,
+  # and we load all of them.
+  #
+  # In my testing this increased the process size by about 3.9 MB (after the conversions array
+  # is GC'd) and took around 170ms to run, which seems acceptable for a workaround.
