Nope, there is a particular gain: in ns or ms needed to finish the program. The MDot on left side of assignments adds time needed to finish, albeit a minimal span. So anyone wishing to spare the CPU unneeded heat should delete those in runtime (for me, reading speed of such code is also markedly improved, as any dot on left side of assignment defaults into objects)

Nope. Those carry no penalty in runtime. MDot on left does.
