Unhelpful exception error messages, e.g. "TypeError: 8" when calling function on custom object #81

Would love to see exceptions thrown by the runtime updated so they have helpful messages. This would make it a lot easier to figure out why they have been thrown without needing a deep understanding of IronJS' internals.

Using the wiki article Create a custom javascript object, I created my first custom object for use my with my JavaScript context. Construction of the object worked fine, but when I called the method LoadURL on my object, the following exception was thrown:

Exception thrown: IronJS.UserError: TypeError: 8 at IronJS.Hosting.FSharp.run(Delegate compiled, T t) in C:\Users\otac0n\Projects\IronJS\Src\IronJS\Hosting.fs:line 151 at IronJS.Hosting.CSharp.Context.Execute(String source) in C:\Users\otac0n\Projects\IronJS\Src\IronJS\Hosting.fs:line 240 at ...

Debugging eventually revealed that it was my fault - I messed up the casing when calling my custom object's only function, but this took me a while to realise due to the obscure error message.

This is a duplicate of: https://github.com/fholm/IronJS/issues/50 I'm going to close this as such.

Would you mind posting this on that issue? We appreciate your feedback, but we don't want duplicate bug reports floating around.

Thanks!
