Feature request: names(someEnv) same as ls(someEnv)

Hi,

I would be nice if names() returned the equivalent of ls() for
environments.
Wouldn't that just confuse people into thinking that environments are 
vectors?  Wouldn't it then be reasonable to assume that 
env[[which(names(env) == "foo")]] would be a synonym for env$foo?

I don't see why this would be nice:  why not just use ls()?
