For the simple grammar like this:

(id)
(inst ("if" exp "begin" insts "end")
      (exp))
(insts (insts ";" insts) (inst))
(exp (exp "." id)
     (id ":" exp)
     (exp "=" exp))
(exps (exps "," exps) (exp))

And lexer rule that overrides braces with begin/end tokens, for example
like this:

((looking-at "{") (forward-char 1) "begin")
((looking-at "}") (forward-char 1) "end")

When trying to indent such construction:

if true {
    bar
|}

I'm recieveing indentation request for :close-all '}', but no such
token was returned by lexer, full log:

forward: 19 -> 20 = end
backward: 20 -> 19 = end
backward: 19 -> 18 = ;
backward: 18 -> 15 = bar
backward: 15 -> 9 = begin
backward: 9 -> 4 = true
backward: 4 -> 1 = if
:close-all '}'; sibling-p:t parent:(nil 1 if) hanging:nil == nil
backward: 20 -> 19 = end
backward: 19 -> 18 = ;
backward: 18 -> 15 = bar
backward: 15 -> 9 = begin
backward: 9 -> 4 = true
backward: 4 -> 1 = if

This is not enough info: we need the complete code so we can run it on
our side and single-step through it to see what's going on.

Sorry for the delay. I have attached full code of the swift-mode with
minimal smie implementation. I didn't clean other pieces of the mode
like syntax table and highlighting code, hope this won't be too
inconvenient to work with.
