What's up with that 'filename syntax?
If memory serves right it's Symbol in Scala which is about the same as
string constant. The assumption is that compiler is aware of all symbols
used in a program and keeps them interned at all times.

Differences are minor, I think the snippet tries to show that the
library supports both.
I guess the code works by having an implicit conversion from String and
Symbol to some PathSegment type from string and overloading / operator
for PathSegments. Since there is no / for basic strings Scala as usual
tries all implicit conversions of arguments to find the proper method.
All of this implicit conversion to some other type on demand may sound
scary and is very much unlike D's way of extending existing types with
UFCS. IMHO it's more powerful but more prone to abuse.
