Controllable Copper Golems for the "Combat and Tinkering Update"

Considering the expected technological potential of copper, and the theme of the new update, now is the perfect time to reintroduce the copper golem with better capabilities.

I propose that Copper Golems be programmable with some basic form of block code, something along the lines of Education Edition's robot. Copper golems could be able to automate almost any action if the player is creative enough, allowing previously monotonous tasks to be a thing of the past. The new golems could be powered by coal, be given gear, and oxidize until they no longer function.

People could use this to make automation easier and less expensive, allowing them to put their skills into more complex and practical or exciting things.
