Re: new function

interesting discussion about "scope", note i'm not saying i want Scheme+ act as Python, i'm still thinking the best solution... to be sure about terminology i find this good article about scoping: https://medium.com/altcampus/scope-local-global-and-lexical-e164f53450b3 Damien On Wed, Sep 22, 2021

Re: new function

yes i know parsing the whole code is the only portable solution, but it is slow,even on a few dozen of lines the slowing is visible ,so i can even think of that on one thousand lines... I finally succeed in Guile with simple piece of code to make my example run with a single assignment operator <-

Re: new function

yes it can reuse an upper and precedent definition but a nested definition can not be used later at an upper level. anyway it would not be portable , for all those reason i will use to separate operator ,basically <- for set! and <+ for define ,so i can even modify toplevel bindings , i did not wa

Re: new function

yes i'm using GNU Guile 3.0.7, https://www.gnu.org/software/guile/docs/master/guile.html/Syntax-Transformer-Helpers.html i have tested a lot , even define-once again and i choose to use to assignment operators and portable code because the non-portable function do not bring more, finally it was no

Re: new function

so i drop off the idea of a single assignment operator, there will be 2 ,<- for single assignment when the variable has been previously defined (at upper level), and another <+ that add a variable in the environment using define. Other possibility is to have a single assignment operator <- and to d
