But you are suggesting it should be string concatenation.
It is already in use for attribute access, as you can see -
and one writting a program, or reading one should not
have to be thinking """ah - but here I can't use the "." because
I am concatenating a string in a variable, not  a literal
string""""

What is that? One thing that works in a way for literals and
in another way for expressions?
Sorry, but there is onlye one word for this: Insanity!
