Regarding single-letter variables, mathematical functions might be an exception. I think writing func gcd(a, b int) int {...} is better than other alternatives. There is simply no need to assign any more meaning to the arguments other than their type.

Maybe if you - and more importantly, everyone that will read the code in the future - are comfortable with domain-specific expressions like that. It depends on the audience really.

As an extreme example, scalaz is similarly a very specialized DSL. Or in my personal experience, functional constructions like map, flatMap, foldLeft and reduce (which I never learned in school).

no, it's not. bigger deal is that single letter vars make it much harder to search for variable usage in files using arbitrary editors.

[coldtea]

Don't use arbitrary editors, or editors that don't support "search for standalone identifier" (e.g. surrounded by space, in (), with ; after etc.".

What would be the signature of your gcd function ?

[base698]

Numerator, denominator?

[mrgriffin]

For GCD? I would find those names very misleading since semantically the order of the arguments to GCD is irrelevant (even if in the implementation you typically mod by b there's no reason you couldn't mod by a).

[sacado2]

This is not mathematically correct. Those names would be pretty misleading, actually.

Good luck with any bigger equation then
