Considering that we're talking mainly about differences of width and 
precision (e.g. the differences between a string and a record are more 
clear) this can probably be improved without considering Delphi here, 
because this is nowhere documented... (our non-generic overload 
selection might lead to different results after all as well) But even if 
we only improve this for non-Delphi modes I agree that a suggestion like 
yours would be an improvement.
