it's not a grammer thing its a sematics (meaning) thing. I must have been programming in C for too long; it doesn't look in the slightest bit peculiar to me!

It's probably as simple as Dennis Richie didn't see a need for it. 

C statements usually expand to very little machine code. Array 
assignment would expand to quite a lot. Though this arguemtn is 
undermined by the observation that struct assignment, which is 
allowed, also expands to quite a lot of code.

I suspect the semantics of array argument passing would become a 
bit messy. You don't really pass an array argument to a function, 
ot "decays" into a pointer. I suspect array assignment would have
quite a ripple affect through other parts of the language.
