I don't think highlighting tokens that are only lexically relevant but
not syntactically relevant is a good idea.
E.g. it's good to highlight keywords because they determine structure.
It's good to highlight strings and comments because keywords within them
*don't* determine structure.
It's good to highlight identifier definitions because these are
semantically important and they tend to be a bit like section titles, so
syntactically meaningful.

But it's not useful to highlight all identifiers, or all numbers, or all
separators, or all infix operators, ... because that doesn't help the
user navigate his code.
