Comment(by simonpj):

 Good point.  I think you expectation is that, with layout braces inserted,
 it'd look like this:
 {{{
 x = if { | False -> if { | False -> 1
                          | False -> 2
                        }
          | True -> 3
        }
 }}}
 No semicolons (there are no semicolons between the guards of a multi-way
 case.  Now it is quite unambiguous, even if it was written all on one
 line.

 This looks reasonable to me, if someone would like to try it.

 Simon
