[...]
5. If strict is false, then
[...]
d. Repeat while thisLex is not the same as varEnv,
i. Let thisEnvRec be thisLex's EnvironmentRecord.
ii. If thisEnvRec is not an object Environment Record, then
1. NOTE: The environment of with statements cannot contain any
lexical declaration so it doesn't need to be checked for
var/let hoisting conflicts.
2. For each name in varNames, do
a. If thisEnvRec.HasBinding(name) is true, then
i. Throw a SyntaxError exception.
b. NOTE: A direct eval will not hoist var declaration over a
like-named lexical declaration.
iii. Let thisLex be thisLex's outer environment reference.
