We ought to update our code and parser to follow this.

Subject: RE: Class static blocks
Static blocks are anonymous parameterless functions. "var" hoists
to the top of these functions (as in any other functions); "static"
is disallowed (because it's legal only on class attributes); and
other binding forms that are legal in functions ("function", "let",
"const") are legal.

Jeff,
What happens to "var" declarations inside a static block?
Are they converted to static declarations or disallowed?
Similarly, I presume a redundant "static" attribute inside a
static block is allowed.

I wanted to clarify the meaning of a static block. Consider:

origin = 0
}
}
Reading the latest draft of the grammar I'm assuming that you must
now put static init code inside a static {} block. Is this correct?
That is correct.
Does that mean that other directives outside of methods and static
blocks are instance initialization code?
No, statements are no longer allowed at the top level of a class
definition.
Class initialization code goes in 'static {...}' blocks,
and instance
initialization code goes in constructors, of course.
Multiple 'static
{...}'
blocks are allowed.
