Can the variable be assigned?

[Arlen22]

I don't understand the details of proposals very well, but is this the equivalent of a const declaration? I'm assuming that's supposed to be the case, but I couldn't find anything in the proposal, unless I'm not understanding technical jargon.

Yes, using x = ... behaves like const x = ... except that when the initializer runs, so long as the result is neither null nor undefined, the declaration captures the x[Symbol.dispose] method to be invoked at the end of the block.
