You may not know this, but POSIX doesn't forbid extensions. Bash in
POSIX mode does NOT cripple all extensions, merely those that are
incompatible with POSIX.  That's why so many people end up writing
#!/bin/sh scripts with bashisms, then get surprised when they break on a
different shell.

If you want a STRICT shell, Debian's posh is even better than dash at
ferreting out use of non-portable extensions.
