Editorial: Don't use dot access in most places #90
Conversation
I believe none of the other instances of dot access are for "concepts" but please correct me if I'm wrong |
So accessing dictionary members through dots is also wrong. Dictionaries are to be treated as maps. I think the only correct dot usage is in serialization and deserialization. |

Rebased this on the infra changes introduced in #95 (and updated to remove use of dot access in most places, as you suggest in your last comment). PTAL? |

is a [=/dictionary=]*
We don't know the dictionary type at this point. Existing issue though so feel free to file a follow-up. (Or I could.)

Sounds like we can't check the specific type (i.e. WriteParams) of a union? Just the data structure (i.e. dictionary/boolean/etc)
Would you mind filing a follow-up?
1. If |input| is `undefined` or |input| is a [=/dictionary=] and | ||

[=/reject=] |p| with a {{TypeError}} and abort these steps. | ||
1. Let |writePosition| be |stream|.[=[[seekOffset]]=]. | ||
1. If |input| is a {{WriteParams}} and |input|.{{WriteParams/position}} is not `undefined`, | ||
set |writePosition| to |input|.{{WriteParams/position}}. | ||
1. Let |oldSize| be |stream|.[=[[buffer]]=]'s [=byte sequence/length=]. | ||

|input| is a [=/dictionary=]; otherwise |input|. |

FYI: this is a no-op, but which allows us to check [=map/exists=]
rather than rely on the dictionary access returning undefined
This reveals a separate issue that |input|
comes from "converting to an IDL value" algorithm, which appears to be able to return both null
and undefined
? Is that a problem?
I've left it as-is for now so that this CL can remain "Editorial" but happy to address this in a follow-up if it's a problem

not sure whether this counts as a non-editorial change... the previous text assumes this to be true

Removing one might not be, but adding one seems fine.
Feel free to merge if this looks good. Thanks! |
