Not only, as said.

It seems like a waste of time to fix inlining of that particular kind of lambdas (and I think it wouldn't be nearly as simple as this) when the end result is only less versatile and clumsier to write.

Other kinds of lambdas, like e.g. those commonly used with map() and filter() would still not be possible to inline, btw. For that to work we'd have to change map(), filter(), etc to special builtin constructs.
