Olivier found out the following fact:
As stated in sections 2.1 and 2.13.4 of the C++ standard, adjacent
string literals must be concatenated during the translation phase.
const char* s = "bon" "jour." "\n";
is equivalent to:
const char* s = "bonjour.\n";
Here is the difference in the AST:
StringLiteral(STRING-LITERAL("\"bon\" \"jour.\"
\"\\n\""))
vs
StringLiteral(STRING-LITERAL("\"bonjour.\\n\""))
Is it parse-cxx job to perform this concatenation, using a desugaring
filter?
No. We can stay with it. It is simple enough.
