Subject: 6.10.3p10: Clarifiying arguments vs. parameters

Summary

Obviously, what appear in the definition syntax of a function-like macro are not its arguments, but its parameters. On the other hand, what is similar syntactically to a function call is obviously the invocation of the macro, not its definition. Clearly, there is confusion about whether this sentence is talking about the definition or an invocation.

Perhaps it would be clearer yet to say something like, "a function-like macro which takes arguments, similarly syntactically to a function call".

Suggested Technical Corrigendum

Change 6.10.3p10:

A preprocessing directive of the form

# define identifier lparen identifier-listopt ) replacement-list new-line
# define identifier lparen ... ) replacement-list new-line
# define identifier lparen identifier-list , ... ) replacement-list new-line

defines a function-like macro with arguments parameters, similar syntactically to a function call.
