luamin doesn't understand t()
luamin doesn't understand that t() is a built-in method in Pico8 and replace it with a "random" function call.

This code:
```
function _update60()
	t()
end
```

minifies to:
```
function _update60()
	a()
end
```

resulting in a:
`attempting to call global 'a' (a nil value)`
