FWIW, I still think the Google Style Guide banning UDLs entirely is too harsh. I think they should be used sparingly, but there are cases where they make sense.

In Chromium's UI code, we have a lot of APIs that deal with coordinates, which may be in either px or dp. And we have a lot of code that needs to hardcode various constants, e.g. layout values for different dialogs. IMO, it's sane to have UDL support here, e.g. `20_px` (at least if we had separate types to represent these two things, which we don't... don't get me started).

Agree. I love UDLs, use them in my code for improved legibility. I hadn’t realized how badly you can screw up if you don’t define all the operators correctly.
