* VError([cause], fmt[, arg...]): Like JavaScript's built-in Error class, but
* supports a "cause" argument (another error) and a printf-style message. The
* cause argument can be null or omitted entirely.
*
* Examples:
*
* CODE MESSAGE
* new VError('something bad happened') "something bad happened"
* new VError('missing file: "%s"', file) "missing file: "/etc/passwd"
* with file = '/etc/passwd'
* new VError(err, 'open failed') "open failed: file not found"
* with err.message = 'file not found'
