That feels like it should be a compiler warning.
I'm now of the opinion that the {} delegates should be deprecated
(instead use () {} delegates)... this comes up a lot and there's a few
other places too where it is a pain... and it isn't that worth keeping
imo.
I didn't even know you could create a delegate with just {} and no
parens. Kinda confusing since, normally, {} by itself creates a scope,
not a delegate.
Indeed:
{int x = foo; return x;} // scope
auto dg = {int x = foo; return x;} // delegate
The requirements seem to be that you have to use the {} syntax as an
expression instead of a block.
omitting the initial parentheses seems like a really low benefit to
having such confusing ambiguity. And of course, it leads to the horrible
examples shown by OP.
