Re: Review of std.signal

[Robert]

This is really ugly, but I don't see any way to improve it either. Maybe

if the type of &classInstance.method was actually a special
"pointer-to-class-method" type that implicitly down-casted to a

delegate, it would be possible to safely use &o.watch instead...

I agree. Is the only reason to have a weak connection?

Yes. Weak connections are the only reason.
