Automatically insert a matching brace in Vim

Question

I spend way too much time fumbling around because Vim doesn\'t handle closing braces like most IDEs do. Here\'s what I want to happen:

Here is what I have in my vimrc:

let s:pairs={
            \'<': '>',
            \'{': '}',
            \'[': ']',
            \'(': ')',
            \'«': '»',
            \'„': '“',
            \'“': '”',
            \'‘': '’',
        \}
call map(copy(s:pairs), 'extend(s:pairs, {v:val : v:key}, "keep")')
function! InsertPair(left, ...)
    let rlist=reverse(map(split(a:left, '\zs'), 'get(s:pairs, v:val, v:val)'))
    let opts=get(a:000, 0, {})
    let start   = get(opts, 'start',   '')
    let lmiddle = get(opts, 'lmiddle', '')
    let rmiddle = get(opts, 'rmiddle', '')
    let end     = get(opts, 'end',     '')
    let prefix  = get(opts, 'prefix',  '')
    let start.=prefix
    let rmiddle.=prefix
    let left=start.a:left.lmiddle
    let right=rmiddle.join(rlist, '').end
    let moves=repeat("\", len(split(right, '\zs')))
    return left.right.moves
endfunction
 noremap!  ,f   InsertPair('{')
 noremap!  ,h   InsertPair('[')
 noremap!  ,s   InsertPair('(')
 noremap!  ,u   InsertPair('<')

And, for some filetypes:

inoremap { {o}O

// I know that InsertPair function is trivial, but it saves time because with it I can define both command and normal mode mappings with one command without having to write lots of s.
