And even without 'scope' in this case the compiler could detect that the delegate doesn't leave the function scope and optimize away.

The compiler currently doesn't do anything with local delegates
declared with 'scope'. It only seems to do anything special if 'scope'
is used as a parameter storage class.

Oh indeed ;)
