I have a piece of code that looks like this:

If I change that "first" function to look like this:

@property ParamCursor first ()
{
assert(any, "Cannot get the first parameter of an empty parameter list");

foreach (c ; this)
return c;

assert(0);
}

Then the last assert is hit. The return statement ends the foreach-loop
but it doesn't return from the function. I have not been able to create
a small test case for this.

Have I done a mistake somewhere or is this a bug in DMD?

Mac OS X, DMD 2.059 or 2.060.


int opApply (Delegate dg)

    auto result = clang_visitChildren(cursor,

    return result == CXChildVisitResult.CXChildVisit_Break ? 1 : 0; //
