Comment #6 on issue 1838 by address@hidden: Make accidental styles available  
as context mods
http://code.google.com/p/lilypond/issues/detail?id=1838#c6

Add Scheme context-mods, reimplement \grobdescriptions, add \settingsFrom

\settingsFrom translates music with layout instructions (\set, \unset,
\override, \revert) into a context modification.  That way, you can use most
of the definitions from ly/property-init.ly as context modifications.

The original task of Issue 1838 can now be solved by writing

\layout {
  \context {
    \Staff
    \settingsFrom #(set-accidental-style 'dodecaphonic)
  }
}

{ fis fis fis fis }

This particular patch uses #{ \with { } #} at some places which, while
nice to have as a last resort, is actually quite awkward.  Neil, could
you turn your original definition of ly:make-context-mod into a
separate commit?  Personally, I'd say that this part of your work has
been up for discussion long enough not to warrant opening another
issue and countdown before pushing to staging.
