Space before the opening [

In this example

Post.find_by_sql ["SELECT title FROM posts WHERE author = ? AND created > ?", author_id, start_date]

The array is a parameter, so a space is required before the opening [, which is equivalent to write like this

Post.find_by_sql(["SELECT title FROM posts WHERE author = ? AND created > ?", author_id, start_date])
