function a(t) return cos(t), sin(t), 1 end

vx,vy,vx+=a(t)

Thanks, nice notation!  Adds our friends += etc and makes them do the obvious Lua thing!

 

Of course, there's a typo in that line, so it will actually expand as: 

  vx=cos(t)+1

  vy=sin(t)

Perhaps we should take this as a cautionary tale illustrating the pitfalls of excessive shorthand :-)
