Matlab has cells and the full object-oriented layer nowadays. There
are short ints, strings, complex numbers, etc. The extensibility is
good. The overall consistency is reasonable.
Syntax for 3D arrays?
Give me one single language where this is natural and immediate.
We are 2D readers/writers, our way of presenting information is
2D within a text editor, and similar problems hit everywhere. I used
3D matrices for the image synthesis, for colour image processing,
for simulations of physical systems. It wasn't worse, and even better
than in many other languages.

Since you vaguely remember something you are thankfully away
from, I believe I can continue to "endure my pain" and I can assure
all the other readers of this text from the perspective of somebody
who uses Matlab *NOW*, that this "pain" is supportable. Optional
The vectorized "comprehension" expressions are really neat.
>In contrast, Mathematica has a pretty consistent and elegant language.
Since I respect others' religions I won't argue. But I hope you don't
try to convince us that Mathematica is good at number crunching...
