the issue here is the name

list

.

x

,

y

, or

foo

would be equally informative….

that's an issue, but not the issue, plus this is an example, I also name my example variables like this when showing code for illustration. And it's not the issue because with

attendeeNames: List<String

it would've been the same, when both fun param and member property have the same name.

exactly - either don’t name them the same or use

this

. if you’re at the bottom of your function and forgot that you local is called the same as your field, your function is too long. could be e.g.

newAttendees

or

replacement

or something
