But if you performed a real benchmark on the code and found out it really needed to be optimized it does not classify as 'premature'.
I'm ok with that since in this very special case speed is more important than readability

certain things like res and i are so common that I'd consider them expressive variable names, but there's not many. For res, I really like the pascal feature of assigning to the subroutines name, because presumably that's already a descriptive name for the result value.
re not liking low level languages, it seems to me like high- and low-level languages have completely different appeals (I happen to like both of them), so one might like one but not the other. Thinking in systems and poking at bits are as much different areas as back-end and front-end.

what is 'i' ?
what real world entity does it represent ? the letter 'i' ? Why would you compare a letter with a number ?
Considering the example talks about C,
i
is probably a counter variable for a numeric loop.i think we should name it 'counter' or 'index'
We are doing software, not math
My real code uses the variable name
res
.github.com/usnistgov/ndn-dpdk/blob...
That
likely
is not "premature optimization". This code is for a high speed router that processes millions of packets per second.I don't know what 'res' stands for.
But if you performed a real benchmark on the code and found out it really needed to be optimized it does not classify as 'premature'.

res
means result. It is common in C code.ok. that's why i don't like low level languages. They are more cryptic.
I try to specialize on higher level languages. Most code smells apply to them.
I suggest not to use 'res' 'i' ir 'result' as variable names since they have no business meaning.

you are absolutely right. They are different tools for different purposes
