Using lambdas in 2.068 becomes painful:

    }
    void bar() {

        auto arr2 = [4, 5, 6];
        arr1.map!(i =>
            arr2.map!(j => baz(i + j))
        );
    }
}

void main() {
}

Error: pure function 'bug.Foo.bar.__lambda1!int.__lambda1.__lambda2'
cannot call impure function 'bug.Foo.baz'

That seems like a bug, I see no pure in sight there, the compiler 
shouldn't infer pure if the inferred function is calling impure functions.

Also after switching to dmd 2.068 I got many stupid errors in lambdas
(defined inside class non-static functions):

Error: need 'this' for '...' of type '...'

I have no idea how to fix it and had to go back to 2.067.

Can you post an example?
