ports and reserved words

[Craig Bilner]

I'm probably missing something obvious here but when my port is a record with an attribute of `class` it comes through as `undefined`. Is there some documentation somewhere outlining reserved words in this area? Should the compiler throw?

Thanks

I had a similar problem with a field named `default`. I think you have to avoid all Javascript reserved words for records passed through ports.  http://www.w3schools.com/js/js_reserved.asp

It is an unfortunate leak of Javascript constraints into the Elm world. It does seem that the compiler could warn about such cases as it knows exactly which types of values are going over ports.
