   A function that calls itself without end now stops with an error that names the call and its line, instead of crashing (branch tickets-a).

   Test:

   1. Run a file with down(n) { return down(n + 1) } and console.log(down(0)).
   2. You see "Recursion too deep: the call to down ran out of stack" with file:line, exit code 1, no crash trace.

   Also covered now (commit on branch tickets-a): a class that constructs itself in a member default, and a getter that reads itself. Both stop with a located error naming the class or the member, instead of crashing.

   Test:

   1. A file loop.hl with next = new Loop(): the error names 'Loop' at that line.
   2. A getter get deep() { return this.deep } read once: the error names 'deep'.
