> According to 14.3.2p1, "a template-argument for a non-type, non-template

See the end of that bullet:

"expressed (ignoring parentheses) as &id-expression, except that the & may be
omitted if the name refers to a function or array and shall be omitted if the
corresponding template-parameter is a reference"
