lyluatex: wrapper with both lilypond code and optional arguments

[Malte Meyn]

Hi list,

I have the following problem: I want to use a wrapper for the ly 
environment that contains some \layout code, music function definitions 
etc. *And* I would like to use lyluatex’s label argument. Any idea how 
to do both? The following example shows both a ly environment with label 
and a wrapper called “aly”. But I haven’t found a way to label the aly 
environment.

Thanks in advance for any hints and help!
Malte
