[swift-evolution] ternary operator ?: suggestion

2) "then" would serve a way to differentiate the If statement and an if

1) I think that making an if-then expression would be less problematic than
making all if else statements into expressions. It was really easy for rust
to just drop ?: because they already had *if* as an expression but in swift
the *if* is a statement.
In swift we have if let and if case; adding if then to handle ternary
operations is probably no so bad.
