That's me then. I consider it good practice and many others do so as well. If it's a constant unchanging value I'll declare it as a const and in capitals only. The length of the function is immaterial - you are signalling the intended use to the developer and the compiler. > Maybe you code like that all the time but I cant say I have seen that > before...

Well, you've interpreted my const comments as a lack of knowledge about classes. It doesn't say anything about me, because it's completely the wrong assumption.
