Comment (by simonpj):

 Thanks for the heads-up.  Can anyone point me to a single write-up of
  * The basic idea
  * A specification, as precise as possible.  (E.g. given a proposed Core-
 Core transformation, does the transformation meet the specfification or
 not?  There are a lot of side conditions like "if `tickishSoftScope`
 then..." in the code.)
  * An overview of how the implementation works
 supported by examples.

 There are lots of related design ideas sketched here
 [wiki:ExplicitCallStack].  If there's a serious proposal to adopt this
 one, it would be helpful to have a write up in at least this level of
 detail, perhaps more.  Maybe it exists already.

 Simon
