I don't understand how that would handle &$... cases.

If it was possible, I'd rather nothing to the left of the right-most sigil was 
highlighted (only $var was highlighted for @$var). It makes the additional 
actions to the variable more visible, look at how *$var and \$var are currently 
highlighted. So I have no problem with only supporting &var, but keeping the 
\$? would be fine too.

And ([$@%]|&\$?)... might be faster than [$@%&]\$?...
