digitalmars.D.learn - What is the extension of ".pdf"

Hi,
I try to solve the puzzle 
https://www.codingame.com/training/easy/mime-type but have some 
issue because std.path:extension returns null for file name 
".pdf" while the puzzle (test case 3) expects that the extension 
is ".pdf".

Is the puzzle wrong or the phobos extension implementation?

Kind regards
Andre

The implementation is very likely thinking of Unix dotfiles, like
.bash_profile, where the intent is to hide the file from normal
displays rather than suggest an extension.

I don't see a mention of dotfiles in the source, but it has these
tests:

     assert(extension(".foo".dup).empty);
     assert(extension(".foo.ext"w.dup) == ".ext");


 Kind regards

Thanks a lot for the explanation, yes, that make sense.
