In previous conversations, I believe "can it be linted?" has been proposed as the question to be asked for this kind of thing.

+1 
many languages have thrived despite not mandating a "self." prefix, and it has not caused all software written with these languages to be bug ridden catastrophies. Lint seems like a rational place to resolve these stylistic preferences.

The problem can also be easily mitigated by having the IDE use a different color to display a variable based on where it was defined (eclipse come to mind as an example). This is something the brain naturally notices without paying any conscious attention.
