For what it is worth, my list of "languages every developer should learn" is:
Learn C, and then an assembly language, to teach you the fine details of how
machines work inside — and because knowing something at that level is going to
be of ongoing value to you over the years.
When you understand how to implement your own thread library you probably know
it well enough to get by.
Learn a functional programming language, ideally a Lisp or Scheme, including
their macro transformation languages and styles. You probably know it well
enough when you look at languages adding syntax for something and die a little
bit inside. (Writing your own meta-object protocol is a good step, too.)
Learn a stack-based language, like PostScript or Forth; the later is a better
choice, since it is the same idea as Lisp but the literal opposite
implementation decision. You probably know it well enough when you understand
exactly why Forth and Lisp are the same idea, differently spelled.
based object system is cool, since it is the third of the two OO styles.

*nod* Though, recent Java has moved to introduce more features like closures,
so they are not /entirely/ blind to the attraction...
