    Error, ReferenceError, etc. are given a stack property that gives a
    stack trace.  Here's an example stack trace:
    
    ReferenceError: FAIL is not defined
        at Constraint.execute (deltablue.js:527)
        at Constraint.recalculate (deltablue.js:426)
        at Planner.addPropagate (deltablue.js:703)
        at Constraint.satisfy (deltablue.js:186)
        at Planner.incrementalAdd (deltablue.js:593)
        at Constraint.addConstraint (deltablue.js:164)
        at Constraint.BinaryConstraint (deltablue.js:348)
        at Constraint.EqualityConstraint (deltablue.js:517)
        at chainTest (deltablue.js:809)
        at deltaBlue (deltablue.js:881)
        at deltablue.js:888
    
    If Error.prepareStackTrace holds a function this function is used to
    format the stack trace, for instance allowing code generators to
    customize the way stack traces are reported to make them easier to
    process.
    
    Next step: performance measurements to see if it is feasible to turn
    this on by default.
