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.]
