FWIW, this seems to stem from the fact that you don't get any sort of
implicit constructor for structs, i.e. you can't embed NSPoint(x, y)
in your code... this has annoyed me on hundreds of occasions; I can't
even begin to imagine what the creators of C were thinking when they
overlooked this.**
So you can't write p = NSMakeLine( NSPoint(50,50), NSPoint(100,100) );
Couldn't a smart compiler, just as it turns NSPoint(50,50) into the
direct-assignment statements, do something similar to this (in
something almost resembling ARM assembly):
mov r0, #50
mov r1, r0
mov r2, #100
mov r3, r2
bl NSMakeLine__10NSMakeLine_I__T13
mov <p>, r0
