Javascript error reporting: show the expression that caused an error.

  • This is how Opera reports javascript errors (in the console):
    "Uncaught TypeError: undefined is not a function"

    And this is how Safari does the same thing:
    "Uncaught TypeError: undefined is not a function (evaluating '')"

    This little extra piece of information is saving me a great deal of time when developing large scale javascript applications. Please add it to Opera.
