Is learning C really a must for a programmer?

Many have this opinion. Somehow, by doing manual memory management allocation and garbage mangement one would become a better programmer.

I have little experience in C mainly because I can write terser and more readable code in Racket or Haskell. However I'm willing to give C a try just to learn these lessons that everybody keeps talking.

But I have a sneaking suspicion that I already know most of what is there to know. Can you list some useful lessons that a typical high level code dweller would be oblivious of?

And how is that supposed to help your case? It perfectly illustrates your fallacy. Slavic languages might have better
theoretical grounding but in practice their value compared to English is insignificantly small because nobody uses them for anything significant.
English is easy to learn but hard to use. Slavic languages are hard to learn but easier to use. So yes, nobody will ever use Slavic languages beside Slavs. Of course there languages like http://en.wikipedia.org/wiki/Ithkuil which are even more flexible than Slavic, but they aint free and you wont get one as a birthright.
