Then don't use this point to sell it to that manager.

I already knew from the start that you had a bad experience in this
area. ;)

Of course you don't want your car built partly with metric and partly
with English measured parts.
<http://en.wikipedia.org/wiki/Metrication> But that is not what this is
about. The feature is not designed to crash a spacecraft, but of course
somebody will still use it for that.

That will not change.

I like it that Perl5 and C go so well together. I dislike Java, so I
don't care for it.
Let's just make Perl6/Parrot the ultimate Cobol "shell" as well.
