Re: dynamically replace = to " = " when followed by [A-z0-9]

How about something like this:

inoremap <silent> = =<Esc>:call <SID>replaceEqualSign()<CR>a
fun! s:replaceEqualSign()
let pos = virtcol('.')
let n = substitute(getline('.'),'\v([A-z0-9])\=','\1 = ','g')
call setline('.',n)
call cursor(line('.'), pos + 2)
endfun
