*location* is a procedure (used for accessing the fluid %location local
to the guile module), not a location. So call it.
Of course, you can just pipe
m =
#(define-music-function (parser location)()
(ly:warning-located location "Replace me")
#{ \melisma #})
through
convert-ly -f 2.19.20 -t 2.19.30 -
and see what comes out.
I get
convert-ly (GNU LilyPond) 2.19.32
convert-ly: Processing `'...
Applying conversion: 2.19.22, 2.19.24, 2.19.28, 2.19.29
\version "2.19.29"
m =
#(define-music-function ()()
(ly:warning-located (*location*) "Replace me")
#{ \melisma #})
