"this" is associated with mutation. Elm is an immutable language.
In theory, one could have immutable objects where data and logic are grouped together. The best expression I've seen so far is the FauxO system in Gary Bernhardt's Boundaries talk. Something like this would constitute a non-trivial expansion of the language and, as far as I can understand it, there are other priorities.
