...onParser) you could use something like this:
$ rake user:create -- --user test@example.com --pass 123

Why does Environment.Exit() not terminate the program any more?
...-duck out. It implements the Visual Styles theming API and is used by this test program. I can't be sure, but my money is on that one as the source of the problem. The copy in C:\WINDOWS\system32 has version number 6.2.9200.16660, created on August 14th, 2013 on my machine.

Finding what branch a Git commit came from
... command works like a charm:
git name-rev <SHA>
For example (where test-branch is the branch name):
git name-rev 651ad3a
251ad3a remotes/origin/test-branch
Even this is working for complex scenarios, like:
origin/branchA/
/branchB
/commit<SHA1>

iPad/iPhone hover problem causes the user to double click a link

Haven't tested this fully but since iOS fires touch events, this could work, assuming you are in a jQuery setting.
$('a').on('click touchend', function(e) {
var el = $(this);
var link = el.attr('href');

Why should I care about lightweight vs. annotated tags?
...e only other thing I can think of is some sort of stamp of approval from a test suite. Have a look at git.git's tags: they all just say something like "Git 1.7.3 rc1"; all we really care about is Junio Hamano's name on them.

PHP foreach change original array values

$fields[$key]['value'] = "Some error"...
