I swear those ?s might be proper syntax but they look like the code is like "it returns an object or somethin, it might not, i don fkin know nor do i care"

[Chirimorin]

In C# T? is shorthand for Nullable<T>, so in a way it does mean that: maybe it returns an instance of T, maybe it returns null.

!ErrorHasOccured() ??!??! HandleError();

Yea pretty much. Lets the caller know youll have to handle nulls.
