Yes, and I don't think it's a good ideas that some people want
to impose such rules.

OTOH, 8rino asks about "your favorite way"  which is much less
stringent than "rules" and rather a matter of preferences.

My personal taste / opinion is to *not* use long variable names,
and I do work with "." here, where other people would prefer
other letters/styles.
E.g., I typicall call most of my data frames  
and then, the models I fit to this data, something like
etc; but all this depends on the circumstances and I'd always
"allow myself" to differ from such a scheme whenever I see

One good reason for the above scheme is that you want names that
differ rather in the beginning than in the end, so
seems less sensible to me -- both for reading and for writing
such code.
