To rephrase my point a little: this is emergent behaviour with an 
obvious cause—a logical not always comes before a comparison.
A problem I have actually had is not being able to parse the 
operation order for expressions like `1 + 2 * 3`, but I don’t 
think we should require parenthesis there either.
Also, here’s a nice case where I’d actually want to write this: 
`!myInt == myBool` Again, here the parenthesis would just be 
visual noise.
