import { funcref } from "https://deno.land/x/denops_std@v3.6.0/function/mod.ts";
Just like |function()|, but the returned Funcref will lookup the function by reference, not by name. This matters when the function {name} is redefined later. Unlike |function()|, {name} must be an existing user function. Also for autoloaded functions. {name} cannot be a builtin function. Can also be used as a |method|: GetFuncname()->funcref([arg])
