Message: [QUOTE="Shao Miller, post: 4223551"] Forbidden? "... The rank of _Bool shall be less than the rank of all other standard integer types. ..."[6.3.1.1p1] That is a discussion which concludes with the definition of "the integer promotions." Then we have for '|'[6.5.12p3] that the "usual arithmetic conversions" are performed, which in this case includes the integer promotions[6.3.1.8p1]. So using '_Bool' doesn't appear to be forbidden. Perhaps your discussion partner believes that the construct "ought to be" ("should be" makes me think that something "is already true," given some reference) because any non-value bits in a '_Bool' are not very useful in a program. However the value is stored, it undergoes the integer promotions and is not longer a '_Bool' by the time it's used in the context you provide, as far as I understand it. [/QUOTE]
