I do not buy this ;) no one knows what they will use (if ever), but still I
see no real reason for blocking this. Following yours logic any of
management operators should be also prohibited in Delphi mode because some
similar feature for nullable types is planned for Delphi (but no one knows
the final form of their Initialize/Finalize equivalent). Code in r39045 is
IMO too strict.

and the same sentence is true for the syntax for static array constants
inside dynamic array constants, the more Delphied syntax for arrays
probably wouldn't provide problems in the future too :)

If you like very strict approach and you want to make our life simpler
probably you should implement some "modeswitch" for allowing both examples
(example with records and arrays).

btw. the problem for different syntax between Delphi and ObjFpc is still
valid. I don't see any real gain for different syntax. It was consulted
with community or this is just individual decision? (and here sorry if I
overlooked something).
