* for freeze (snowflake)

[goodwin64]

As for me, * character fits better for freeze operation

const foo = {*
  a: {*
    b: {*
      c: {*
        d: {*
          e: [* "some string!" *]
        *}
      *}
    *}
  *}
*}

This is much better. I also think {** ... } should deep-freeze.

Given that ({*x(){}}) is valid syntax now (creates an object with a generator method called x), this may be non-trivial to parse.

And frozen generator will make code reading a hell 😈

Agree, closing
