Right. The second one is also in the syntax font, so it is a more formal
definition of what is being talked about. (The Standard often uses the
English equivalent of a syntax form, but those are rarely if ever defined.
We tend to change them when we see them for a better formal definition,
although there are some cases where that's wrong. [Specifically, "function
call" is generally thought to include infix operators, while the syntactic
"function_call" definitely does not include infix operators. The fun of
maintaining a Standard.]
