It is, indeed... Thanks!
Now, why can this snippet not be found when searching for "lazy
evaluation" and "late evaluation

That's not "like a real variable as known from other programming
language". If I write
aaa = 3

In LilyPond terms, in
namedMusic = { ... }
'namedMusic' is called a variable, identifier or macro.
Normal LilyPond behaviour is
aaa = { c4 d e f }
bbb = { a4 a a a \aaa b4 b b b }
\score { \bbb }
This produces { a4 a a a c4 d e f b4 b b b } .
Now I want to re-use bbb with a different
