I did not ask for general syntax suggestions. What I am asking about
is specifically what the preference people might have between these
two options:
fn(params) => expr
|params| => expr
As well as potential issues (thanks, Ilija, for pointing out a
theoretical issue with union types).

As a disclaimer I'm trying to guide the discussion to these two
options, not suppress suggestions I don't like.
