Seeing an odd bug in Android Studio 2.3.3 on OS X El Capitan and Kotlin plugin 1.1.3-release-Studio2.3-2. If I use an extension function within a property where I'm using an expression AND an implicit type, the IDE doesn't seem to be able to resolve the extension function. If I convert it to a block body and then back to an expression, it works. Hopefully the gif will illustrate it better than my description.
