Python strings are immutable, but only sometimes

This is outside of the spec... "is" is for testing the exact same reference and it is only coincidence that to speed things up they made smaller integers the same objects in memory. See:

    >>> a=257
    >>> b=a
    >>> a is b
    True

What you want is double equals.

He names references in his post. I highly doubt he’s confused about the difference between is and ==. It’s a weird leak of interpreter details that could, in very narrow situations, cause a bug.

The language never said you could do this.
