Found this while trying to wrap() the vim.ui.input offered by dressing.nvim, as it actually overrides the value with a table that implements `__call` instead of an actual function.

Replace [curl wrapper](https://github.com/krady21/compiler-explorer.nvim/blob/master/lua/compiler-explorer/http.lua) used for making REST API calls with internal version once such interface is provided in neovim. [Tracking issue upstream](https://github.com/neovim/neovim/issues/23232)
