get({func}, "name"): is it behaving correctly?

[Ernie Rael]

Doing

def T()
enddef
echo T->get('name')
echo T
finish

produces this output

<80><fd>R34_T
<SNR>34_T

Is this expected? I just saw `T->get('name') and thought I could
use it to replace a spot where I'm extracting the name from `string(T)`.

I get:

E121: Undefined variable: T
E121: Undefined variable: T

When I prepend "vim9script" then I do get the output you mention.

The output looks OK, you get the internal name of a script-local
function. Either the byte-code version or the printable version with
<SNR>. Note that you can also get the printable version with:

echo function('T')->get('name')

Thanks. Now I get it; it's magic. (easier for me to understand than delving
into byte-code version and what I'd do with it.)

Never having learned vimscript, seems there are some things I'm not
easily getting a feel for, since with vim9script...

See ":help get()" and go down a few lines.
