uri routing to index()

[eluser]-sek[/eluser]
The CI documents give the routing as

class/function/param/param/ etc.

Working on a new class, I noticed that I was getting a 404 Error with

/friends/pending/

friends is the controller class and pending is the parameter.

After puzzling with this a bit, I discovered CI apparently does not honor the routing convention for the index() function.

I didn't want a url like

friends/friends/pending
or
friends/browse/pending

Just

friends/

for the default listing and

friends/pending

for the pending listing.

I know that I can put the code into another function, browse() or friends() and specify a routing that does not mention the function name, but it seems strange that I can't pass a parameter to index().

Any ideas?
