Re: passing vim9 vars to python3

• From vim9 help I see Functions and variables are script-local by default

             So s: is no mandatory no?, because if I put s: I see E1268: Cannot use s: in Vim9 script: s:yml_f = yml_fpath.

• So I delete s: and obtain this

           3.12.0b1 (tags/v3.12.0b1:5612078, May 22 2023, 16:20:31) [MSC v.1934 64 bit (AMD64)]
           <vim.dictionary object at 0x0000020790DC9380>

          regarding this code : 

            vim9script

            def Py3_SimpleMinimalTest(yml_fpath: string): void
              var yml_f: string = yml_fpath
              exe 'py3 print(sys.version)'
              exe 'py3 print(vim.current.buffer.vars)'

              exe 'py3 print(vim.current.buffer.vars[''yml_f''])'
           enddef
           Py3_SimpleMinimalTest('foobar.yml')

         Then I got 

          3.12.0b1 (tags/v3.12.0b1:5612078, May 22 2023, 16:20:31) [MSC v.1934 64 bit (AMD64)]

          <vim.dictionary object at 0x0000020790DFFF00>
         Traceback (most recent call last):
         File "<string>", line 1, in <module>
         KeyError: 'yml_f'

Do you mean you want to access variables local to a compiled function by
name? That is not possible. The "l:" namespace that exists in legacy
functions was intentionally left out in compiled functions, because it
adds quite a bit of overhead. You can use a script-local variable to
make this work. It does mean you go outside of the function scope, but
it's still inside the scope of the script file. That means it won't
interfere with what happens in other scripts.
