Of course it's ECMA-compliant, and it does exactly as it's being told.
Nothing about the behavior described is at all what I or any other
programmer possessed of all his faculties should expect.

It was a logic error, not a language or implementation bug. Inspection
of the logic in the code makes that pretty clear, and it's either
[excess] laziness or [excess] hubris that obfuscates it.

When you redefine a variable, you should expect its old value to be
removed. Few languages (see also: PERL::Tie) behave otherwise, unless
you deliberately overload the assignment operator.

Look at the code again and actually step through what each line does.
You know. Debug it. Then point out exactly where the language is
behaving as it ought not, or not behaving as it ought, and why.
