in reply to Weird File::Basename::basename

Is this a bug?

Yes , I think so.

See, its a typical bug (if a boundary condition isn't tested, chances are it'll be broken)

OTOH, on the scale of importance/severity, I would classify this bug as unimportant

FWIW, you should perlbug it just the same :) functions should do what they claim to do -- and they might as well explicitly spell out what that is instead of merely referring to the manpages -- I'll bet if the pod actually spelled out the full behaviour, there would have been a test for it in the test suite :)

    On the importance of this bug: In a way "./" is the neutral element in pathes in the sense of adding it anywhere in the path does not change anything (except in the middle of a name obviously).

    One exception springs to mind: When executing a command it does make a difference whether to say

    system("somecommand"); # or system("./somecommand");

    Whether or not this can happen due to the usage of basename('') in any practical example I am not sure.

      When executing a command it does make a difference whether to say "foo" or "./foo"

      not on cmd.exe, cwd is first place searched

      :) spec/basename are useful, but they're kinda low-level, I prefer abstractions like Path::Class and Badger::Filesystem and absolute paths, so file( ... )->absolute
