4. Let inMethod be false.
5. Let inConstructor be false.
6. If thisEnvRec has a [[HomeObject]] field, then
a. Let inMethod be true.
b. If thisEnvRec.[[FunctionObject]] has a [[Construct]] field, let
inConstructor be true.
7. Let script be the ECMAScript code that is the result of parsing x,
interpreted as UTF-16 encoded Unicode text as described in 6.1.4, for the
goal symbol Script. If inMethod is false, additional early error rules
from 18.2.1.1.1 are applied. If inConstructor is false, additional early
error rules from 18.2.1.1.2 are applied. If the parse fails, throw a
SyntaxError exception. If any early errors are detected, throw a
SyntaxError or a ReferenceError exception, depending on the type of the
error (but see also clause 16). Parsing and early error detection may be
interweaved in an implementation dependent manner.
