The LFE Style Guide takes inspiration (and often times actual content) directly from key sources in the Lisp, Erlang, and even Clojure developer communities. These are as follows

Note, however, that these are not considered sacrosanct sources of ultimate truth; (and neither is this guide). Instead, they contain practices that we have either adopted as-is, modified to some extent, or simply rejected (e.g., due to prior conventions established in MACLISP and LMI Lisp, their inapplicability due to LFE's unique status as a Lisp and Erlang dialect, etc.).

In general we suggest following the LFE style as outlined here if you are creating a new project. If you are contributing to a project maintained by someonoe in the community, we recommend consistency: using the style adopted by that project (for any contributions to that project).

Above all, enjoy the parenthesis.
