Or python, which is where the author is coming from. In python there are fewer syntactic ways to write the same thing (semicolons aren't optional, they're just not permitted. The only ways to write and and or are 'and' and 'or', '&&' and '||' simply don't exist. Map literals always look like {key1: value1, key2: value2}, the braces are non-optional ).

Even python's critics would admit it's a very readable language, and it would be unusual to claim it's not expressive.
