+Let's say you want to make use of `ignorecase` as that's what you'd like when searching with `/` and `?`. However you then realise how oddly pervasive this setting is in that is applies to things like `:s`. Rather than inserting "\C" into every pattern you think you'll use use an autocmd and so some up with something like the following config.
+
+```vim
+set ignorecase
+
+autocmd CmdLineEnter : set noignorecase
+autocmd CmdLineLeave : set   ignorecase
+```
+
+Only to find it doesn't work, `ignorecase` still seems to be in effect when using `:s`. This is because `CmdLineLeave` fires not only before you truly leave the command-line but also before the command has executed.
+
+Here's a snippet to overcome this in a generic fashion by using a timer.
+
+```vim
+let [s:ignorecase, s:smartcase] = [&ignorecase, &smartcase]
+
+function! s:RestoreCase(ID)
+    let [&ignorecase, &smartcase] = [s:ignorecase, s:smartcase]
+endfunction
+
+augroup SaneCase
+    autocmd!
+    autocmd CmdlineEnter : set noignorecase nosmartcase
+    autocmd CmdlineLeave : call timer_start(100, '<SID>RestoreCase')
+augroup END
+```
+
+The far reaching effecting of `ignorecase` annoys me enough as it is but `CmdLineLeave` firing before executing the command really takes the biscuit here.
