People sometime try to fix things they don't understand.  For example, some
people mistakingly assume the `dojo/_base/array` functions should behave
like the ES5 native functions, but it is because they predate the ES5
standard and we can't change them without breaking compatibility.

So, it is to encourage people to first get their bearings before flinging
PRs at us.  I have reworded it an update to the PR.
