Yield break with return value

[jagorath]

When breaking an iterator, two statements inside a code block are required, e.g.

if (someCondition)
{
    yield return -1;
    yield break;
}

With a combined return/break statement for example called "yieldlast" (or something less awkward), these four lines could be reduced to one -

if (someCondition)
   yieldlast -1;

Or to avoid new reserved words, yield break could have an optional parameter:

if (someCondition)
   yield break -1;
