why () is () and [] is [] work in other way?

Funny, Haskell frequently beats C in both categories.  MATLAB is
faster and more memory efficient than naive C matrix code, since it
has a very efficient copy-on-write implementation.  As the various C++
matrix libraries will show you, efficient COW is much harder when you
have to deal with C++ aliasing rules.

Alas, these two are probably true.
