 ### Lifetime parameters
 
-In contrast to `Ty`/`Const`'s `Param` singular `Param` variant, lifetimes have two variants for representing region parameters: [`RegionKind::EarlyParam`] and [`RegionKind::LateParam`]. The reason for this is due to function's distinguishing between [early and late bound parameters](../early-late-bound-params/early-late-bound-summary.md) which is discussed in an earlier chapter (see link).

 `RegionKind::EarlyParam` is structured identically to `Ty/Const`'s `Param` variant, it is simply a `u32` index and a `Symbol`. For lifetime parameters defined on non-function items we always use `ReEarlyParam`. For functions we use `ReEarlyParam` for any early bound parameters and `ReLateParam` for any late bound parameters. Note that just like `Ty` and `Const` params we often debug format them as `'SYMBOL/#INDEX`, see for example:
