What's the most common convention for naming files containing strictly extension functions?

fooExt.kt

FooExt.kt

, etc?

FooExtensions

FooExt.kt

FooExtensions.kt because long names are not boring. 😅

FooExt.kt or just Ext.kt

I’ve seen lower case names where the contents are package level functions since the package string is in lower case

so, module level functions, because it's kotlin? :troll:

internal

breaks down pretty fast when your teammates don't realize that Gradle source sets are the same target
