           Summary: Improve TypeError description to be useful
           Product: WebKit
           Version: Other
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2

Evaluate [a] = {a:1} in console. It produces the following less than helpful error:

        TypeError: undefined is not a function (near '...[a]...')

We should explore improving this error.
