Useful indeed! It still strikes me as weird that one will need to add this check
many times when porting code from Delphi, but at least now one can.

Jonas will probably argue that this is a tautology and should always evaluate to
true because a variable of a type by definition is of that type, regardless of
content, but it might be considered as somewhat in line with how "var is class"
handles nil values as "not an instance of class".


Ceterum censeo b32079 esse sanandam.
