vim.fn.remove: does not remove item

[randomizedthinking]

Describe the bug

When using vim.fn.remove to remove items from a list, it does not do the job.

Steps to reproduce

nvim --clean
:edit foo.lua
local list = {1, 2, 3}
vim.pretty_print(list)
vim.fn.remove(list, 0)
vim.pretty_print(list)
:w
:source %

Expected behavior

It is expected the list value to become {2, 3}, yet the value is still {1, 2, 3}.

Neovim version (nvim -v)

0.8.2

Vim (not Nvim) behaves the same?

not tested.
