No, that's not what I'm doint.
That's exactly what xxx=\context{..} does now. And by storing the whole 
context, it will later on reset the whole context to the settings when the 
assignment was done (in particular the \RemoveEmptyStaff context saves the 
status of the \Staff context during lilypond's initialization and later on 
simply applies all these settings, reverting later manual changes to \Staff...

My patch only stores a list of context modifications, without a particular 
context attached. Think of it as storing just the contents of a \with block. 
E.g.

xxx = \with {
  \remove Clef_engraver
  \consists Ambitus_engraver
}

That reasoning was also my motivation to not reuse \with, but add a new 
keyword (although \with also works in this situation and is treated in the 
parser just like the \contextmodifications keyword).
