I found that it would be more satisfying to the user if :match and :syn had additional attribute, 'priority=', so that user could control what has higher prio and what has higher prio.
I find current rules of assigning priorities ad hoc and too user-uncontrollable. For :match, they are fixed and not changeable. For :syn match(syn keyword etc), they depend on the order of execution and on something that I don't even know. In one specific case, I see that ':set list' suppresses ':match'. This is not user controllable. I'd prefer that by 'priority=N' in :match I could say whether it tops ':set list' or not, and that I could do it for :syn match, too. Thanks
