ELIXIR CLOSES COMPLETION AND OPERATOR SIGNATURE GAPS

The Elixir team shipped fixes for two long-standing IDE friction points: cursor completion after operators and proper type signatures for the ++ concatenation operator.

Developers using IDE completion in Elixir will see immediate relief with the fix to cursor positioning after operators [1]. The patch treats trailing operator keywords as completion fragments when they follow another operator, surfacing relevant suggestions instead of dropping them. In parallel, the team resolved the ++ operator signature issue [2], which was causing compatibility check failures in to_existing_atom/2 and leaving the operator without proper documentation in type specs. Both fixes target developer experience at the editor level, the kind of polish that compounds across thousands of daily interactions. Neither breaks existing code. Both land in the next release cycle.
