Subject: File.join edge cases

Hi all,

Ruby 1.8.2
Solaris 10

Here are some edge cases I thought were interesting...

File.join("")       # ""    - ok
File.join("", "")   # "/"   - huh?
File.join(nil)      # ""    - expected a TypeError
File.join(nil, nil) # "/"   - wha..?  again, expected a TypeError
File.join(1,2)      # "1/2" - expected a TypeError
File.join("/")      # "/"   - hrm, ok, but...
File.join("/", "/") # "//"  - could be smarter

I'm surprised that File.join stringifies all of its arguments.  May I ask why 
that approach was taken?

Mainly I posted this just to see what folks thought about it.

Regards,

Dan
