# Gamma Scheme γ-Scheme is an implementation of R7RS with delimited continuations. The current focus is to make it run in a host Scheme interpreter, which can run procedural macros and `syntax-case`. It is called "gamma" because metacontinuations in [Dyvbig, Peyton Jones, and Sabry][1] are labled γ. [1]: https://dx.doi.org/10.1017/S0956796807006259
