import { test_garbagecollect_now } from "https://deno.land/x/denops_std@v5.2.0/function/vim/mod.ts";
Like garbagecollect(), but executed right away. This must
only be called directly to avoid any structure to exist
internally, and v:testing must have been set before calling
any function.
This will not work when called from a :def function, because
variables on the stack will be freed.
