<dsmith>In Guile the *unspecified* that (if #f #f) returns is used by the REPL to *not* print the expressions value

<lloda>imo using (if #f #f) as an idiom is a awful idea

<wingo>to me it is harmless but silly

<bryce_m>I should go to bed. (let ((str "world")) (string-concatenate '("hello " str)))

<bryce_m>In procedure string-append: Wrong type (expecting string): str

<lloda>you have to write `("hello" ,str)

<lloda>else str is a symbol not a variable reference

<bryce_m>lloda: Thanks. Yeah, I'm stumped as to why I'm failing to see the effect of the quote in this case. To bed.

<shawnw>Or (list "hello" str)

<lechner>Hi, some conditions don't change while a program is running. Can 'eval-when' help to more speedily direct calls to code intended for particular machine types?

<dsmith>sneek, later tell lechner Pretty sure eval-when only knows the symbols eval, load, compile, expand

<sneek>Got it.

<dsmith>sneek, later tell lechner See https://www.gnu.org/software/guile/manual/html_node/Eval-When.html#index-eval_002dwhen Best not to experiment if you have a cat

<sneek>Got it.
