Re: [fpc-pascal] Multiple active class helpers at same time

Is planned support for multiple class(objet, record) helpers in a way, that all class helpers can be used in parallel not only one? Yes, it is planned. Main problem currently (aside from time) is to define when a method hides the method of another helper, especially when inher

[fpc-pascal] Multiple active class helpers at same time

Hi , I am sure that this was already discussed, but I can not find any conclusion. Is planned support for multiple class(objet, record) helpers in a way, that all class helpers can be used in parallel not only one? My use case is: In unit A I have declared base class. In unit B I have dec
