Issue ID: 20653
Summary: Short-circuiting boolean logic not working
Product: D
Version: D2
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P1
Component: dmd
Assignee: [email protected]
Reporter: [email protected]
I feel like this should work:
enum Thing { A, B }
enum IsThing(T) = is(T == enum) || (__traits(getLinkage, T) == "C++");
enum Is = IsThing!Thing;
> Error: argument to `__traits(getLinkage, Thing)` is not a declaration
> Error: template instance `IsThing!(Thing)` error instantiating
`is(T == enum)` is true, so it shouldn't attempt to evaluate `getLinkage`.
