>          Components: examples
>            Reporter: james strachan

>             Fix For: 2.18.0

> e.g. so folks can type things like
> {code}
> from("seda:cheese").
>   filter(m -> m.getHeader("foo", int.class) > 5).
>   map(m -> createPurchaseOrder(m.getBody(Invoice.class)).
>   to("seda:bar");
> {code}
> Note if the current Predicate/Expression classes don't work as lambdas we could add a new interface with a single method to the DSL to ensure Java 8 does the right thing with lambdas
