I wonder is it possible to add position information to the error message?

Unbalanced delimiter found in string
    at Function.XRegExp.matchRecursive (node_modules/xregexp/lib/addons/matchrecursive.js:211:15)

Something like

Unbalanced delimiter found in string, for left delimiter at position 123

So that it's easier for user to find out where is the problem in the input string.
