Expression Semantics ---------- -------------------------------------------------------- C::labels An MPL Sequence of Integral Constants
I think that a case should only have a single label. Allowing multiple labels makes the implementation harder without adding any significant utility. See below.
case_<I>(f) Returns a Case object with supplied <snip more generators>
These can return fusion sequences of cases instead of plain cases. This has the additional benefit that switch_ can be specified as taking a fusion sequence of cases, without having to handle a single case specially.
default_(f) Returns a Case object with an empty labels list. forwarding to the encapsulated function object f.
From the standpoint of the implementor of switch_, how do I figure out which Case is the default?
* case_c and case_range_c are simple shortcuts. The type of integral constant is int. The actual type can be casted to the actual switch parameter. I think this is safe
Since the value is known at compile time the cast can be checked at compile time to detect overflow. In Christ, Steven Watanabe
