To quote the Boost.Local docs:
Unfortunately, there are intrinsic limitations to the amount of syntactic
error checking that can be done by the parsing macros implemented using the
preprocessor. As a consequence, an error in using the parenthesized syntax
might result in cryptic preprocessor errors. The best way to identify and
correct these errors is usually to visually inspect the signature comparing
it with the parenthesized syntax grammar (see the Grammar section). When
syntactic errors can be detected by the parsing macros, they are raised at
compile-time using error messages of the form ERROR_description_text."
