Pre-RFC: flexible `try fn`

[newpavlov]

@phaylon

And I hope that there’ll at least be the compromise of not turning wanting to write Ok and Err into warned behavior.

I haven't seen anyone talk about such extreme proposals. As you can see, try fn will be desugared into explicit Ok and Err. The closest thing is @scottmcm's suggestions to restrict ? to try context, but:

• It will discussed only in preparation to post-2018 epoch.
• I am not sure if it will find enough support. (I am personally pretty much undecided on this right now)

Open question: How to handle return without semicolon?

Originally I suggested something very similar to you proposal, but this questions is the biggest stumbling block. Plus even one keyword is a heavy price to pay, nevertheless two.
