Differentiate between methods and functions

[warpkanal]

I initially filed this issue against vscode microsoft/vscode-go#1923 but understood that it's more a problem in the parser than in vscode.

I'd like to treat method vs. function invocations differently.
This is for example possible in Goland:

Function invocations on some package (e.g. time.Now()) can be rendered differently than method invocations on some receiver e.g. (now.Day()).
I find this quite helpful in distinguishing the two.

Would be awesome if the atom go parser would support this!
