Now, someone *could* write a tokenizer that took care of string
concatenation on the spot--as long as it dealt with comments as well:
("abc"
# hello
"def")
It would be even possible to write a parser that didn't have a separate
lexical analyzer at all.
Arguing about terminology is pretty useless. Both sides in this fight
are correct, namely:
* string literal concatenation is part of expression syntax
* what goes on inside an atom stays inside an atom
For example, this expression is illegal:
"abc" ("def")
