If so, what are the challenges towards creating a general purpose python ffi for Racket? As someone else who does a lot “guerrilla” Racket programming as an engineer in a large (non-software) company, it would be extremely pleasant to have easy access to the plethora of more standard scientific tools available there (and thus also to those available in R, and MATLAB, through libraries like RPy) for prototyping but without leaving the comforts of DrRacket.<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; ">Kyle Andrews<o:p></o:p></div><div style="margin-top: 0in; margin-right: 0in; margin-left: 0in; margin-bottom: 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif; "><o:p> </o:p></div></div>____________________<br> Racket Users list:<br> <a href="http://lists.racket-lang.org/users" style="color: blue; text-decoration: underline; ">http://lists.racket-lang.org/users</a><br></div></span></blockquote></div><br></body></html>
