Why can't the compiler do something similar automatically. Then we
won't have
the problem if a lambda returns void or a value.
1. This can get arbitrarily expensive if there are parameters involved
(temps have to be constructed, copied, & destroyed) and those costs will
be hidden.
I guess so.
2. At some point, heroic efforts to coerce one type to another will
subvert the point of a type system. After all, if the designer of bar()
intended the return value to be the point, wouldn't such a conversion
hide a bug?
Maybe, but so could not using the returned value as well.
It sounds so easy in my head.
