Conditional access

In X# you can use a conditional access to an object.

Instead of writing

if oObject != null
  oObject:ExecuteMethod()
endif

you can write

oObject?:ExecuteMethod()

This means that there will be no exception in the case oObject is null. Of course this works not only with methods, but also with properties (and access/assigns):

oObject?:MyValue := cMyValue
