A simple synchronous JSON-with-comments loader that gives good explanations of where failures come from.
It accepts a superset of JSON including Javscript style comments (
/* */ and
var loadJsonicSync = ;var result = ;
loadJsonicSync will throw an error if loading fails. The error will show the
filename, for context, and
error.cause() will show the original exception
which includes the position for parse errors, and the underlying fs error if
there is a problem reading the file.
