I have no idea what you want.  Music functions are called when parsing
LilyPond source code.  At that time, there are no contexts and no
context properties.  Consequently, music functions have no way
whatsoever to read or modify context properties.  All they can do is
create music expressions (typically overrides or applyContext calls,
possibly as context modifications) that contain callbacks of some form
that, when ultimately called during iteration of the music expression,
will be able to access actual properties.

So for your actual question, there is little insight and instruction to
be had.
