The acronym "HOT" was coined by Bob Harper at CMU. We used this term
mainly because it best characterizes the set of languages that we
are interested in (e.g., ML, Java, Haskell, and safe C).
Will FLINT support every HOT language in the world ? probably not,
and we never intend to.

I don't want my project to fail, so guess I have to make sure it won't
be another UNCOL project :-)
Actually, I do agree with Dwight that C is a great universal
intermediate language. It probably did not meet all the goals set by
some of the UNCOL projects, but the compiler community has benefited
greatly by compiling their own language into C and then use the C
To some degree, FLINT wants to be a universal *typed* intermediate
language. By "typed", I mean that certain important properties (e.g.,
type safety, security) of the FLINT program can be statically verified
at compile time or link time. A unified type system also provides
better support to interoperability and system-wide garbage collection.
Here, simply taking the type-safe subset of C is not enough because it
does not provide adequate support to many features in advanced
Finally, a common *intermediate* language does not have to be like
those fat, multi-paradigm imperative/object-oriented/functional/logic
programming languages. We have had compilers that compile ML, Haskell,
Ada, Java to C, yet C is still a relatively simple language.
