@Mangdries Python devs are really obsessed with what is correct according to what their holy book PEP says

They have a whole book to tell them how to write code and it still looks horrible

that’s actually a really cool trick — the many with-usages (like locks!) are a huge boon to understandable code.

And while it took me 25 lines of code to implement this with with wisp ( https://hg.sr.ht/~arnebab/wisp/browse/examples/with.w?rev=3447d48e85620c639131c0e1b47308503df5eb81#L12 ) it’s only Python where that’s the default way to do things.

(there is no superfluous with in the previous paragraph ☺)

Being able to add stuff like this to the language cleanly is why I started to move my personal projects from #Python to #Guile #Scheme in 2013, though.

Code implementing with: define-module : examples with import : oop goops define : enter thing . thing define-generic enter define : exit thing . thing define-generic exit define-syntax with syntax-rules : as : _ thing as name thunk ... let* : name : enter thing res : begin thunk ... exit thing . res define-method : exit (thing <port>) . "Ensure that a port is always closed at the end of the with-block." close-port thing define : main args with (open-file "with.w" "r") as port format #t "~a\n" : read port
code example: with (open-file "with.w" "r") as port format #t "~a\n" : read port
