/lilypond-git (master)$ git grep 'drumPitchNames'
Documentation/misc/ChangeLog-2.10:      * ly/drumpitch-init.ly
(drumPitchNames): add tamtam.
lily/parser.yy:         SCM nn = parser->lexer_->lookup_identifier
("drumPitchNames");
lily/parser.yy:         SCM nn = parser->lexer_->lookup_identifier
("drumPitchNames");
ly/drumpitch-init.ly:drumPitchNames =

Is not exactly what I would call _under_documented.

Though, I'm not sure I understand all yet.

Do the following two lines the same?
drumPitchNames.bla = #'bla
#(set! drumPitchNames (acons 'foo 'foo drumPitchNames))

How to put in a list? The following looks a bit clumsy.
#(for-each
   (lambda (sys) (set! drumPitchNames (acons sys sys drumPitchNames)))
   '(aa ab ac ad ae af)))
#(pretty-print (take drumPitchNames 10))

Thanks,
