Re: [racket-users] Constructor-style printing outside of DrRacket?

Although it's an old library, you can use `construction-style-printing` and `mzlib/pconvert` to get this effect. Take the following module: #lang racket (require mzlib/pconvert) (global-port-print-handler (λ (data output [quote-level 0]) (parameterize ([current-output-port output]
