Yup.

Well, the real surprise here is the absence of a syntax error. The type
signature is missing after the argument list. If you add (ly:music?)
after (parser location m), the example compiles and does what you want.
It would require a thorough analysis to understand just _what_ this
definition actually does without that.
Of course, it complains about not being able to end the slur that
started inside of the grace note.
