 Creating an empty environment via `ParamEnv::empty` is almost always wrong. There are very few places where we actually know that the environment should be empty. One of the only places where we do actually know this is after monomorphization, however the `ParamEnv` there should be constructed via `ParamEnv::reveal_all` instead as at this point we should be able to determine the hidden type of opaque types. Codegen/Post-mono is one of the only places that should be using `ParamEnv::reveal_all`.
 
-An additional piece of complexity here is specifying the [`Reveal`][reveal] (see linked docs for explanation of what reveal does) used for the `ParamEnv`. When constructing a param env using the `param_env` query it will have `Reveal::UserFacing`, if `Reveal::All` is desired then the [`tcx.param_env_reveal_all_normalized`][env_reveal_all_normalized] query can be used instead.

 The `ParamEnv` type has a method [`ParamEnv::with_reveal_all_normalized`][with_reveal_all] which converts an existing `ParamEnv` into one with `Reveal::All` specified. Where possible the previously mentioned query should be preferred as it is more efficient.

 The type system relies on information in the environment in order for it to function correctly. This information is stored in the [`ParamEnv`][pe] type and it is important to use the correct `ParamEnv` when interacting with the type system.
 
-The information represented by `ParamEnv` is a list of in-scope where-clauses, and a [`Reveal`][reveal] (see linked docs for more information). A `ParamEnv` typically corresponds to a specific item's where clauses, some clauses are not explicitly written bounds and instead are implicitly added in [`predicates_of`][predicates_of] such as `ConstArgHasType` or some implied bounds.

 A `ParamEnv` can also be created with arbitrary data that is not derived from a specific item such as in [`compare_method_predicate_entailment`][method_pred_entailment] which creates a hybrid `ParamEnv` consisting of the impl's where clauses and the trait definition's function's where clauses. In most cases `ParamEnv`s are initially created via the [`param_env` query][query] which returns a `ParamEnv` derived from the provided item's where clauses.
