Tuples and Proplists
Do not align keys and values in property lists; instead, simply use the standard Lisp formatting (e.g, as provided by the LFE Emacs formatter).
Bad:
'(#(k1 v1)
#(key2 value2)
#(key-the-third value-the-third)
#(another one))
Better:
'(#(k1 v1)
#(key2 value2)
#(key-the-third value-the-third)
#(another one))
