Better error messages in Pages

I was creating custom template logic to display a field, and I had a slight syntax error. When submitting the template code I just got the following... decidedly unhelpful error:

At which point my template code was promptly thrown out.

I'd expect to see an AJAX error, at the very least something like "Syntax error" on the same edit page with my code still intact.

Can we get something a little more user friendly here? I mean, I'd like to see a big push for IPS developers to make more useful error messages throughout the suite, but at the very least Pages should have useful errors since it's developer focused.

Thanks.
