That's pretty much my point of view - the compiler should keep you out of trouble but not get in the way.

Colours are the same case as left in the context of textAlign. If we reserved all lowercase alphabetic identifiers, so your vars had to contain an uppercase letter or non letter character then that would 'solve' that problem at the expense of freedom of the coder. (But only for natural languages which have casing!).

So really what we want is 'reserved in context' - the problem there though is the context - in many cases that can only be known at runtime.

In terms of computers driving cars then we let computers monitor and interpret sensors for humans in nuclear power stations. We let them 'drive' very large aircraft and provide simulated feedback and sensor interpretation there to pilots. Same for trains, trams, vehicles in factories and warehouses... So why not cars? ;)

Although that being said - I do have a slight issue with computers driving cars at this point in time - but only because they have to deal with humans driving cars and those pesky pedestrians with free will...

Warmest Regards,

Mark.

In this vein I'm not sure syntax is so important.
