Hi, I'm trying to write a grammar for a scripting language, and to do this I'm building an AST of each expression.  I have this working fine, for the most part, but I've run into a problem -- I can't seem to figure out how to put right-to-left associative operators into the tree properly.  I had this as a guess, but I'm really not sure: r = value | value >> root_node_d[ch_p('=')] >> r;
