Comment #11 on issue 2336 by address@hidden: Patch: Add layout changing  
command \layout-from for getting context defs from music

I don't think that
\midi { \layout-properties-from { \tempo 4 = 80 } }
is clearer.

First, \midi is not \layout.  Second, there is no such thing as either  
layout or output properties.  What is changed are context definitions, with  
_either_ command.  The difference is that the preexisting command produces  
context modifications for a single context definition, while the new  
command modifies several context definitions within an output definition.

Of course, I bungled the syntax in the example: it is not really that  
symmetrical.  You have to write
\midi {
  \Score { \with \context-like { \tempo 4 = 80 } }
}
in order to use the context mod produced by the previous \settingsFrom.
