The reason that I use C many of times is not because of its speed but because it (almost) completely reveals it inner working even when there is clear reason not to do so.

(1) Though it is bad for most of time but still I feel more contended sometimes with it, especially for complex code.

(2) Even if this transparency is at superficial level with optimising compilers, but there are very few high level optimisation applied to C code and that too in the form of loop unrolling, tail call optimisation, loop interchange etc.
