[rust-dev] Specifying lifetimes in return types of overloaded operators

Currently if I try to specify lifetimes in the return types of overloaded
operators like Index ([]), I get an error message :

"method `index` has an incompatible type for trait: expected concrete
lifetime, but found bound lifetime parameter &"

Why has this restriction been placed, given that I can write custom
functions which can have bounded lifetimes specifications in the return
