+
+ * Full Lua compatibility: Easily call any Lua function or library from
+Fennel and vice-versa.
+
+ * Zero overhead: Compiled code should be just as or more efficient than
+hand-written Lua.
+
+ * Compile-time macros: Ship compiled code with no runtime dependency on
+Fennel.
+
+ * Embeddable: Fennel is a one-file library as well as an executable.
+Embed it in other programs to support runtime extensibility and interactive
+development.
+
+Anywhere you can run Lua code, you can run Fennel code.")

2.23.0
Some limitations: (require "fennelview") – i.e. requiring the library distributed with the language – does not work. I spoke with members of freenode's #fennel and a FENNEL_PATH could be added. In a future package definition, wrap-program would set that variable. In the meantime, this can be worked around: fennel --add-fennel-path "$(guix build fennel )/share/?.fnl" No native readline support. I have decided not to package https://luarocks.org/modules/peterbillam/readline as fennel 0.2.1's use of readline does not give more functionality than rlwrap.
