another alternative. in {$H-} no changes string=shortstring, in {$h+}
string = ansistring or unocodestring in delphiunicode mode) by default
but can be redefined directly in code (or this definition is set in
ObjPas unit) "type string = MyNiceStringType". and this redefinition is
inherited from used unit if all of them compiled in {$h+} mode. In other
words if unit has directive {$h-} string=shortstring in any case, but if
unit has {$h+} it use "string" type from used unit as it is regular type.
Defining the "string" type in a unit (e.g. the ObjPas unit) is a bad
idea if you want to keep the capability to change the "string" type on a
per unit base as you can't change the compiled ObjPas unit. Also you'd
need a unit for every string type that should be supported.
The proposal where "string" is changed based on some compiler
option/define is better (though the question about its use or
consequences is still not solved).
