description: Variable collision with lexical binding in lower scope
|

info: |

[...]
|
|
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.
