Currently, an SyntaxError is thrown, but the line and column properties are set to the call site of JSON.parse().
What I really want to know is the string that failed to parse, and where within string parsing failed (approximately).
If the parse error says 'invalid number', I would expect to be able to figure out where it died.
This is kind of difficult since the argument to JSON.parse is generally not a resource we already have in a text editor, so we'd need to figure out how to display that text (which could be megabytes of JSON).
