I've noticed that the first entry seems to always be treated like a pointer no matter what it is. Has nothing to do with `this`. Strings, ints, etc....

That may very well be because I did just recently update dmd and this is when I noticed it... I'm not sure if I updated visual d around that time or not.

Could also be due to updates of Visual Studio 2019: I just noticed that a function wasn't showing any locals. These reappear when setting the VC linker debug option to "FULL". If you are using a visualdproj project you currently have to add -L/DEBUG:FULL to the additional command line options to get the same result.
