388	This rule handles ambiguous cases with operator identifiers, e.g., "int ??()", where the string "??" can be
389	lexed as "?"/"?" or ""/"??". Since it is common practise to put a unary operator juxtaposed to an identifier,
390	e.g., "*i", users will be annoyed if they cannot do this with respect to operator identifiers. Therefore, there is
391	a lexical look-ahead for the second case, with backtracking to return the leading unary operator and then
392	reparsing the trailing operator identifier. Otherwise a space is needed between the unary operator and operator
393	identifier to disambiguate this common case.
394
395	A similar issue occurs with the dereference, *?(...), and routine-call, ?()(...) identifiers. The ambiguity
396	occurs when the deference operator has no parameters, ?() and ?()(...), requiring arbitrary whitespace
397	look-ahead for the routine-call parameter-list to disambiguate. However, the dereference operator must have a
398	parameter/argument to dereference ?(...). Hence, always interpreting the string ?() as * ?() does not preclude
399	any meaningful program.
400
401	The remaining cases are with the increment/decrement operators and conditional expression:
402
403	i++? ...(...);
404	i?++ ...(...);
405
406	requiring arbitrary whitespace look-ahead for the operator parameter-list, even though that interpretation is an
407	incorrect expression (juxtaposed identifiers). Therefore, it is necessary to disambiguate these cases with a
408	space:

410	i++ ? i : 0;
