I don't see a deep conceptual difference between them
The secomd uses a constant where the first uses a variable.
That is a difference in detail, but not a deep difference.
At least, I don't see a deep difference.

I am not entirely sure what that refers to; I am sort-of guessing.
The thing it is treating specially is a string in the expression being
compiled, if I understand what you mean.

This discussion is not about the facts of what happens, if I understand.
It's about the way to conceptualize them.

Yes and no.  Readers who know other languages will get an immediate
understanding from "literal string".  But that understanding is not
exactly the right understanding.  So we ought to correct it
to get to the right understanding.
