These list element variable definitions can be expressed more succinctly with `match-define`. Note that the suggested replacement raises an error if the list contains more elements than expected.
Using `cond` allows converting `let` to internal definitions, reducing nesting
This use of `printf` has no arguments other than the template string.
Internal definitions are recommended instead of `let` expressions, to reduce nesting.
This expression can be replaced with a simpler, equivalent `hash-update!` expression.
Use the `#:when` keyword instead of `when` to reduce loop body indentation.
Internal definitions are recommended instead of `let` expressions, to reduce nesting.
Nested `when` expressions can be merged into a single compound `when` expression.
This use of `define-values` is unnecessary.
These nested `for` loops can be replaced by a single `for*` loop.
(define id/name (place-channel-get local-chan))
(define id (list-ref id/name 0))
(define name (list-ref id/name 1))
(match-define (list id name) id/name)
