Problem: Get E923 when using function(dict.func, [], dict). (Kent Sibilev)
Storing a function with a dict in a variable drops the dict if the
function is script-local.
Solution: Translate the function name. Use dict arg if present.
Problem: Using ":call dict.func()" where the function is a partial does
not work. Using "dict.func()" where the function does not take a
Dictionary does not work.
Solution: Handle partial properly in ":call". (Yasuhiro Matsumoto)
