23.6.47 Positional_Parameters
Flag each subprogram or entry call using positional parameter notation,
except for the following:
- Invocations of prefix or infix operators are not flagged
- If the called subprogram or entry has only one formal parameter,
the call is not flagged;
- If a subprogram call uses the Object.Operation notation, then
- the first parameter (that is, Object) is not flagged;
- if the called subprogram has only two parameters, the second parameter
of the call is not flagged;
This rule has no parameters.
