Comment (by simonpj):

 Great!  Can you also confirm that this change makes `test3` (described in
 comment:11 of #15519, under "Workarounds") work as fast as `test0`; and
 does so
 * WITHOUT removing the INLINE pragma on `testGrammar`
 * Without removing the other uses of `testGrammar1` in (say) `test1`
