Which language would annoy a PHP user?

We have nobody who coordinates the programmers at the company. Everybody uses the technology he wants.

Which programming language would you suggest to learn that would annoy a PHP user (who knows a bit of Java) and give him a bad time if he has to take over a project?

Look up "capabilites" or "tagged architectures" and follow the rabbit hole to know what security might be like in a world that admits that computers should be and indeed are constantly programmable machines.

Well that sure seems more like a problem of architecture.

Bullshit.
It's well know that moot is the one who answers the red phone at FBI HQ.
Are you accusing him of being a double agent?

Yes with regards to the last thing I said. However, all things being equal, a program performing run-time type and bounds checking is always more secure than a program not doing so.

This is why when e.g. compiling C programs optimized for security you pass -fstack-protector-all, NO optimization (or -O0) and you enable mudflap (-fmudflap ?) in GCC.
