OK, I've read http://wiki.freepascal.org/Modernised_Pascal this (and the FAQ as well). I disagree with any statement saying that for .. in loop is only a type-saver. It's a good language extension and should be included (since Delphi already have this, it will also be a good idea). Consider the following example:
type TDays: (Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday); TDaySet: set of TDays; var d: TDaySet; begin for d in [Monday,Wednesday,Friday] do ; // versus for d:=Low(TDaySet) to High(TDaySet) do if d in [Monday,Wednesday,Friday] then ; end; The latter one has iteration overheads, while the former can be optimized to loop as many as needed. I'm not saying I'm the best Pascal programmer, but in case there's a (better) solution to this (rather than extending the language) please tell me. -- View this message in context: http://www.nabble.com/for-..-in-loop-implementation-tp21327686p21327686.html Sent from the Free Pascal - General mailing list archive at Nabble.com. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
