Not just a bash extension, as ksh and zsh have it too, but you are right
that dash doesn't implement it because POSIX 2008 (Issue 7) doesn't
require '==', just '='.  [There is a good chance that the next POSIX
revision (Issue 8) will require '==' as a synonym for '=', but as that
version of POSIX is still several years away, you're still better off
sticking to '=' for now.]
