Step 4 should (its also wrong in ES5 15.3.2.1) be:
<p>If <var title="">body</var> is not parsable as <i>FunctionBody</i> or if
parsing detects an early error then abort these steps.</p>

<p class="note"><i>FunctionBody</i> is defined in ECMAScript edition 5 section
13 Function Definition. "Early error" is defined in ECMAScript edition 5
section 16 Errors.<a href="#refsECMA262">[ECMA262]</a></p>


Step 6 is unnecessary, as the specific strict mode restrictions in ES5 section
13.1 relate to the naming of the formal parameters of a function and the fixed
set of names you provide in step 7 don't violate any of those restrictions.

I agree with the goal, but there are some missing ES semantics we still need to
address. In this particular case, I think we may be able to describe the
desired semantics as a source-to-source transformation of the ES code and avoid
having to explicitly reach into the ES5 internal spec. mechanisms.
