OT: This reminds me of a small benchmark I did recently where using a
signal implementation with two pointers (function and delegate, to
allow connecting to both) is faster than using a single delegate and
converting a function pointer to a delegate via toDelegate(). It
boiled down to:

if (funcPtr !is null)
    funcPtr(...);
else
if (delegPtr !is null)
    delegPtr(...);
