+//
+// However, this file was also very large (over 36,000 lines), and
+// compiling it was very slow, and in fact was a significant
+// bottleneck for incremental rebuilds. To address this, we now
+// generate the file split across multiple shards, named
+// VariableType_0.cpp and so on, which can be compiled in parallel.
+//
+// For ease of inspection and debugging, so that it's not necessary to
+// go rooting around in multiple files, we also generate all the
+// functions together in VariableTypeEverything.cpp. This generated
+// file is only for convenience; it's not actually used in the
+// build. If the file you're looking at now is one of the shards, you
+// may want to switch over to the Everything variant to make you
+// grepping smoother.
