Re: vim function not first-class variable? how to create an alias for vim function ?

Excerpts from pansz's message of Tue Jul 05 10:24:05 +0200 2011:
> I want to do some coding like this:

let F = function('Foobar')

call call(F, [arg1, arg2], { optional self dict })

Note: F must be upper case, cause functions can only be assigned to
upper case vars.

Also see vim-addon-mw-utils (on my github page).

That implements a function reference by using a special key in a dict.
This way you can also add args to the function ref:

let f = funcref#Function('FooBar',{'args': [ 1, 2] })

call funcref#Call(f, [2,3])

will call FooBar(1,2, 2,3)

It also supports kind of eval functions definitions:

let f = funcref#Function("return ARGS[0]")

last but not least obj like functions:

let X = {}

fun X.A(a,b)
echo a:a
echo a:b
endf

call X.A(2,3)
let C = X.A
call call(C,[], X) " or the like
