True, but the issue with them is: you cannot use them to create a fool 
proof read-only property without using a function because there is no 
unit level encapsulation aka private/protected on unit level: the 
variable read by the property cannot be in the implementation part of 
the unit because it wouldn't be accessible at declaration time of the 
property.

Making IsMultiThreaded a function is a no-no: it is used in really speed 
critical code paths and using an inline function neither because it's 
used mostly in assembler code in the rtl like:

if ismultithreaded then
  <do things locked>
else
  <do things without locking>
