Re: \include inside function

[Valentin Petzel]

Hello David,

An assignment basically adds a pair (symbol, value) to some assignment table. 
So shouldn’t it be possible to parse a file with a new assignment table and 
then convert this assignment table into a scheme accessible structure?

I do not mean to say that assignments should not be performed, but that they 
should be performed in a different scope, which we then make accessible from 
the original scope.

This could also enable some sort of name-spacing. Let’s say we have different 
Ly files that were not written with name-spacing in mind and then we want to do 
a project to combine these. Then instead of needing to rename assignment in 
one file we could do something like

fileA = \include "fileA.ly"
\fileA.score

or something, whatever.

Cheers,
Valentin
