Delphi provides two uses clauses in every unit. The discussion, which uses clause is to be preferred, seems to be an old one. There are different justifications which unit clause should be used – regarding code style, circular references, or readability.
The information I am missing is: in terms of compilation time and memory use – where should I put my units if I am free to decide?
Is there a general rule for all Delphi versions or is the behavior different in different versions? I do not know of an official statement from Embarcadero, but I tend to think that putting everything in the interface clause should improve compilation time and memory usage in the IDE.
I do not want to start another discussion about code style and which uses clause to prefer – this was already discussed at length at other locations. I want to reduce compilation time and memory use in large projects.
