+<p>Some backgrounds are discussed in <t>x-asciimath.mkiv</t>. This is a third version. I first
+tried a to make a proper expression parser but it's not that easy. First we have to avoid left
+recursion, which is not that trivial (maybe a future version of lpeg will provide that), and
+second there is not really a syntax but a mix of expressions and sequences with some fuzzy logic
+applied. Most problematic are fractions and we also need to handle incomplete expressions. So,
+instead we (sort of) tokenize the string and then do some passes over the result. Yes, it's real
+ugly and unsatisfying code mess down here. Don't take this as an example.</p>
