            Bug ID: 149134
           Summary: Confusing error message when closing curly brace is
                    missing in a template literal string
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org

STEPS TO REPRODUCE:

Here's a test case that runs in the JSC shell:

>>> var foo = 123; var bar = `aaa bbb '${typeof foo'.`; 42;
Unexpected EOF:1


NOTES:

A useful error message occurs in this use case:

>>> var foo = 123; var bar = `aaa bbb '${typeof foo  ccc'.`; 42;
Unexpected identifier 'ccc'. Expected a closing '}' following an expression in template literal.:1
