synopsis:            A framework for symbolic, homoiconic languages.

description:         H-expressions are a variant of S-expressions. Where s-expressions are atoms or nodes grouped into lists of length at least one, h-expressions, or hexprs, are grouped into lists of length two. This may seem very trivial, but this restriction makes it possible to treat parenthesis in the concrete syntax of hexprs merely as a manual override to the basic precedence rules, just as in mathematics. In particular, a suitable hexpr interpreter is capable of understanding eta-converted terms, which is quite unrealistic, if not impossible in an sexpr-based syntax. Thankfully, hexprs retain all the advantages of sexprs with respect to homoiconic syntax.
                 
                     Hexprs on their own are fairly unhelpful, so we also have also included a configurable hexpr parser based on parsec. I wasn't long before mission creep set in, and a series of tools were produced to aid in creating a frontend for hexpr-based languages. See the package 'hexpr-examples' for some examples of the framework in action.

                     I think H could stand for many things: the greek letter eta, hierarchical, happy, next in the alphabet after f, or perhaps hexpr == hexpr-expression. Where it comes from is unimportant, what is important is that we can easily the next generation of homoiconic languages.
