    Abstract Syntax Tree. That's the structure parsers usually return (but they don't have to, see e.g. my Marpa Enhanced Calculator where the parser directly calculates the expressions without actually building the tree).

    map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]
