関数名に g: は使ってはいけない(確信)

vim-jp – Lingr

That's a bug. A function name should not be allowed to contain a colon.
The intention, as mentioned in the quoted docs, is only alphanumeric
characters and '_', while prepending s: is allowed to make the function
script-local. Something like abc:def() was never intended to work.
