Why? I think that would be a mistake. Roll in any way you wish (after fixing
bugs and all), but do roll it it. There's absolutely never a good reason to
call a pure function and ignore its result, unless you just want to keep the
CPU warm.
Yes there is. In cases where you want to pass an empty delegate
literal to a function which requires a delegate.
Interesting. I wonder whether empty functions should be handled as a
special case or are part of a pattern.
