All review-related feedback on and discussion of the DIP
should occur in this thread. The review period will end at
11:59 PM ET on July 28 (3:59 AM GMT July 29), or when I make a
post declaring it complete.
At the end of Round 1, if further review is deemed necessary,
the DIP will be scheduled for another round. Otherwise, it
will be queued for the formal review and evaluation by the
language authors.
Thanks in advance to all who participate.

Not that it is a requirement to consider fir this DIP, but how
would this play with Vittorio's lambda Value capture DIP(?)?
I don't see any relation. Looks like the lambda capture lowers
to defining a temporary struct and assigning the captured values
to fields in that struct, then the lambda is defined as a member
function of that struct. That member function already uses the
delegate ABI where the context is a reference to the temporary
struct.
void main()
{
int x;
string s;
auto dg = [x,s]() => {
// ...
}
/*
lowers to something like this
struct __lambda_struct__
{
int x;
string s;
// This method already has a context, cannot make it
extern(delegate)
void execute()
{
// ...
}
}
auto dg = &__lambda_struct__(x, s).execute;
*/
}
