I'm trying to get acquainted to the icons of the autosuggestions of the IDE. So far so good: v is a value, f is an array, italic f is a lambda and that odd thing in second place is an array. So far so good...

I doubt f is array, I would think function And italic f probably inline function Not sure what the box is, maybe an overridable function?

I'd guess "inherited" method

sorry with "f" I meant function. LOL it looks like it's not that important
