Hello,
i have released the version 2.0 of Scheme+ for Guile:
https://github.com/damien-mattei/Scheme-PLUS-for-Guile

Scheme+ is an extension of the syntax of the Scheme
<https://en.wikipedia.org/wiki/Scheme_%28programming_language%29> language.

Scheme+ makes it easy the assignment of Scheme objects in infix (works also
in prefix) notation with a few new operators  ← (or  <-), [ ],⥆ (or <+) .

Regards,

Damien
