This can also be done at the LPC level better than ever before:
  * The combination of LWO's and compilation-from-source makes it very 
easy to do things like comparer = Lambda("a", "b", "return a < b;"); arr 
= sort_array(arr, comparer);
  * Long ago, Dworkin posted a full grammar for the LPC language, 
suitable for use in parse_string(). It has a few errors in it, and it 
needs to be updated with language changes since then, but it basically 
works, and parsing LPC is quite fast. We use it at Skotos to parse a 
mutation of LPC. If all compilation went through such a layer first, you 
might be able to add lambda expressions and such at the syntactic level.
