"functions" in lilypond

[Kieren Richard MacMillan]

Hello, all --

I know you can set up predefined "variables" containing a bunch of 
different directives (including notes, tweaks, markings, etc.), but can 
you set up "functions" where the "parameters" can be decided at 
"runtime"?

For example, can I set up a "tuplet within a quadruplet, with slurs 
between notes 2 and 4, a phrasing slur over the whole thing, and a 
crescendo on the last two notes" and supply the specific pitches only 
when I actually use the "stamp":

    \myCoolNoteSetDefinition {bes a c b cis cisis d}

Thanks!
Kieren.
