Xcode9b1 - Would like command-mouse highlighting of objective C structures

Product:Developer Tools Product Version:Version 9.0 beta (9M136h)
Classification:Suggestion Reproducible:Always

When command-mousing around (not clicking) in swift code, it shows the structure (this is _REALLY_ nice. Thank you for this. I like it so much better than the accidental-collapso-ribbon in prior versions)

I'd love to have this in Objective-C.  

Just in case it should actually be working on objc, here's a video:

Steps to Reproduce:
hold down command and mouse over an objc for loop or if statement

Expected Results:
Get cool ephemeral vertical lines like in Swift

Observed Results:
Just the variable names highlight when moused over

Version 9.0 beta (9M136h)
10.12.5 (16F73)


The Swift behavior is what I'd like to have in objective-C land.
