Using bare vars is more efficient because it makes the builtin `math` expression cache more useful. That's because if you prefix each var with a dollar-sign then the fish parser expands it before `math` is run. Something like `math x + 1` can be cached since the expression is the same each time it is run. But if you do `math $x + 1` and x==1 then you're effectively executing `math 1 + 1`. And if x==2 the next time then you're running `math 2 + 1`. Which makes the expression cache much less effective.
