Until now dots were read as symbols.
* guix/scripts/style.scm (read-with-comments)[dot]: New variable.
[dot?, reverse/dot]: New procedures.
Use 'reverse/dot' instead of 'reverse' when reading lists.
* tests/style.scm ("read-with-comments: dot notation")
("((a . 1) (b . 2))", "(a b c . boom)"): New tests.
