No, since the patches are few and far between.

I don't think that's an error in if_lua: the documentation doesn't say
anything about dictionaries not allowing empty strings as keys -- :help
Dictionary only says that 'a key is always a String' -- and hence the absence
of error when printing d in your example. What is not allowed is for you to
read or set empty keys in Vim (using 'let'), but I don't want to replicate
that in if_lua. For instance, you can do this:
vim -u NONE -c 'let d={} | lua vim.eval("d")[""] = "empty"'
-c 'for [k,v] in items(d) | echo "|".k."| -> ".v | endfor'
So, to be consistent, if you set an empty key in if_lua, you can read or reset
it there.

There's no error here either. The problem is that tr() expects three
arguments, and not that the variable must start with a capital letter (g:input
already exists.) Try this:
vim -u NONE -c 'lua vim.eval("g:").input=vim.funcref("tolower")'
-c 'echo input("Yes?")'
I think you're mixing the fact that Vim Funcref variables should start with a
capital letter. Funcrefs in lua are just a value; for instance, this should
work:
:lua print(vim.funcref"tr"("<tag>", "<>", "{}"))
" {tag}
Thanks for the comments!
