Repeated use of the same sqlc.arg() in MySQL generates a struct argument

What happened?

When I use sqlc.arg(blah) twice in the same query and no other parameters, I'd expect the generated query method to have a blah int argument, rather than a arg MyQueryParams argument.

This works correctly for PostgreSQL. (The difference is that Postgres can just repeat $1 in the query and be done. MySQL needs to repeat the ? and pass the value twice.)

Relevant log output

Database schema

CREATE TABLE authors (
  a INT,
  b INT
);

SQL queries

-- name: CreateAuthor :exec
INSERT INTO authors (a, b) VALUES (sqlc.arg(num), sqlc.arg(num));

Huh, this is most certainly a bug.
