When I say 'dodgy', 'scary', and so on, I was not referring to the
underlying idea (attibute selectors) but to the actual characters
representing the operator.

I am absolutely positively supporting the idea of being able to match items
in a space separated list case sensitively, and hyphen separated lists case
insensitvely. Please understand that that is *not* where (IMHO) the problem
lies.

The problem is the actual syntax that has been chosen.

It is these 'short, declarative ways' which are my problem. In four years,
there will be a need for case sensitive, tilde separated matching. And the
logical syntax would be [att~=val].

But we won't be able to use this, and [att?=val] will be selected. And it
will get worse and worse.

We have the option, *now*, to make this system clear and logical.

Well yes, but I am trying to settle for less...
