guix shell sees to it that all of the dependencies (listed in the inputs and native-inputs sections) are available within the shell session it creates by downloading (or building, if necessary) the entire dependency tree.

Should you want/need more isolation from the host system, guix shell has you covered. The --pure flag will clear out most existing environments variables, such as $PATH, so that the resulting environment does not contain pointers to places like /usr. For more Docker-like isolation, the --container flag can be used, which will run the new shell session within a set of Linux namespaces so that the host system is inaccessible.

Guh, someday I am going to have to learn that bracket-based syntax (lisp?) that keeps popping up on particularly interesting projects but I can never be bothered to learn.

it's as simple as

(command argument0 argument1 argument2)

meaning arguments 0, 1 and 2 are applied to command. when an expression is evaluated it dissolves into a value according to its context.

(+ 1 2 3)
; evaluates to 6 in a context where + actually means an addition or sum operation

(* 2 (+ 4 3))
; evaluates to 14 (i think)

the absolute killer feature is the elimination of idiotic, man-made madness excused with the term "operator precedence"
