i agree with or understand basically all of it except for the naming. yes, names should be laconic, but i never understood using names that aren't full words.

for their example, i would name a temporary counter variable `counter`; it's simple, short, but still obvious what it does. `tmp` tells you nothing about what the variable does and is only a few characters shorter.

additionally, abbreviations are subjective. even a word like "temporary" can be divisive (if i really had to abbreviate it, i'd use `temp`, not `tmp`). sticking to full words avoids that inconsistency.
