Discussion:
Increment and decrement operators are missing from Table 88 -- Position type requirements in 31.5.3 [fpos].
Proposed resolution:
Table 88 (section 27.4.3) -- Position type requirements be updated to include increment and decrement operators.
expression return type operational note
++p fpos& p += O(1)
p++ fpos { P tmp = p;
++p;
return tmp; }
--p fpos& p -= O(1)
p-- fpos { P tmp = p;
--p;
return tmp; }
Rationale:
The LWG believes this is a request for extension, not a defect report. Additionally, nobody saw a clear need for this extension; fpos is used only in very limited ways.
