The husk-scheme package
Husk is a dialect of Scheme written in Haskell that implements a superset of the R5RS standard. Advanced features are provided including:
First-class continuations of unlimited extent
Hygienic macros based on syntax-rules
Low-level explicit renaming macros
Library syntax from the R7RS standard
A foreign function interface (FFI) to Haskell
Full numeric tower providing support for real, rational, and complex numbers
Proper tail recursion and lexical scoping
Read-Eval-Print-Loop (REPL) interpreter, with input driven by Haskeline to provide a rich user experience
Standard library of Scheme functions, and support for many popular SRFI's
Husk may be used as either a stand-alone interpreter or as an extension language within a larger Haskell application. By closely following the R5RS standard, the intent is to develop a Scheme that is as compatible as possible with other R5RS Schemes. Husk is mature enough for use in production, however it is not optimized for performance-critical applications.
Scheme is one of two main dialects of Lisp. Scheme follows a minimalist design philosophy: the core language consists of a small number of fundamental forms which may be used to implement other built-in forms. Scheme is an excellent language for writing small, elegant programs, and may also be used to write scripts or embed scripting functionality within a larger application.

Include debug trace statements in compiled code.
Haskell Foreign Function Interface (FFI). Allows husk to import and call into Haskell code directly from Scheme code. Turn off FFI to decrease build times and minimize executable sizes
Turn off pointers to increase performance at the expense of severely restricting the functionality of mutable variables. Setting this flag to false will revert back to the behavior from older versions of husk.
Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
