Simply put this in a mod's data.lua and Factorio will crash when it tries to load the main menu:

data.raw["utility-constants"]["default"].main_menu_simulations = {
	my_simulation = {
		init = [[game.simulation.write{text="hello world"}]] }}

This crash is probably my fault, however there's nothing in the documentation that suggests I'm doing anything wrong:

Ideally though, I would like the game to actually give me an error messaging suggesting what I did wrong.

Thanks for the report, the crash is fixed for 2.0.33. You will have to assign camera_player before calling the function.
