It moves the stratified names out of the syntactic space that JS programmers
typically use for their own names. The Dunder names don't have that characteristics plus
various sort of "_" prefixing is already used by many programmer at the
application level.
Agreed, but this problem will come right back in ES7. Private names don't solve
this issue because of where they trap, so we don't need a temporary patch, but
a permanent solution.
It's even back in ES6 with "then". I find it truly weird that we're trying to use two
different mechanisms to get the <then> and <iterate> metaproperties. We should be
cutting down the complexity, not adding to it in a manner which the unknowns bouncing around this
thread indicate is reckless.
