I am sorry I didn't follow this thread although I am the "OP" :-). If I understand correct, I would suggest NOT introduce the "absolute" keyword, instead, make it ALWAYS absolute. i.e.:
with a = SomeObject, b = SomeRecord do begin ... ... end; Both a and b are "reference" to the object or record, IMO there seems no need to do assignment in the with syntax. Thus, I suggest use = instead of := 2013/3/18 Sven Barth <pascaldra...@googlemail.com> > On 17.03.2013 15:29, Jonas Maebe wrote: > >> >> On 17 Mar 2013, at 15:02, Luca Olivetti wrote: >> >> Al 17/03/13 13:54, En/na Marco van de Voort ha escrit: >>> >>>> In our previous episode, Sven Barth said: >>>> >>>>> >>>>>> Texas Instruments' Pascal had an extension of the with statement, IIRC >>>>>> it used = instead of AS >>>>>> >>>>>> With a=VeryLongNameForARecord, b=**AnotherRecordWithAVeryLongName do >>>>>> ... >>>>>> >>>>> >>>>> Now THAT is really unpascalish... either ":=" or the already suggested >>>>> "as"... >>>>> >>>> >>>> Since it is a pseudo variable declaration, I would assume VAR syntax and >>>> just use ":" ? >>>> >>> >>> That would be consistent with "On E:Exception do writeln(E.message)". >>> >> >> No, because "On E: Exception" says that "E" is of the type "Exception", >> just like in a variable declaration the expression after the colon also >> identifies the type.
