vim-patch:8.1.1834: cannot use a lambda as a method
Problem: Cannot use a lambda as a method.
Solution: Implement ->{lambda}(). (closes vim/vim#4768)
https://github.com/vim/vim/commit/22a0c0c4ecd23b6c43f79ba9b92899ca0b426e29
Add an additional lua_funcname argument to call_func_rettv() to maintain
support for v:lua.
A memory leak was introduced with this patch that was fixed in
v8.1.2107.
