More concise syntax for lambdas

While VB’s use of the full-length Function keyword makes the language easier to approach and learn, it makes it harder to actual work with.

I use linq a lot and when chaining methods the length of the line quickly becomes an issue. I suggest using a conditional contextual keyword Fn, which would be the equivalent of Function if there was no Fn in scope as a compromise between providing context and conciseness and a breaking change.

I am familiar with the history,
