Parameter binding lists should force parameters bindings to be enumerated in source order.

[efaust]

Right now the reference encoder feels free to sort parameter bindings lexicographically, which doesn't play nicely with engines.

[Yoric]

What's the problem, exactly? Default arguments?

[Yoric]

@efaust Is this still a problem? Do you want me to do something about this?

CheckParameterNames checks the order in step 5:
https://binast.github.io/ecmascript-binary-ast/#sec-checkparameternames

and actualParams has names in the syntactical order:
https://tc39.github.io/ecma262/#sec-function-definitions-static-semantics-boundnames

so, if the order doesn't match, it's the reference encoder's bug.
I'll check it shortly

moved the issue to binjs-ref.
I'd suggest closing this issue.
