Lately I'm doing a lot of (x) => { return x.foo(7); } in C# and it's nice to omit the amazingly long type for x. The IDE even knows the type of x for intellisense... I think scala would allow x => foo(7), or maybe even => _.foo(7) or even _.foo(7). I haven't written much scala, so I may be way off...

Recent experiments by myself indicate you cannot omit the type and you 
cannot use auto for the type, so you actually need to type your 
VeryLongClassName!(With, Templates) if you need it.

I sort of miss automatic type deduction.
