metasyntactic variable prenex
Explicitly marks variables, e.g. ko'a ko'e, lerfu-strings, and/or brodV (must be converted into sumti using me'ei) as being metasyntactic: i.e. having no specific meaning or referent and merely used to demonstrate syntax or hypothetical scenarios. Automatically unassigns these variables from any previous assignment. e.g. (me'ei broda me'ei brode ko'a ko'e fo'a fo'e ge'ai). See ge'ei, ce'ai, ke'au, zo'u, da'o
