betaReduceStx — Mathlib

Lean4
/-- `beta_reduce at loc` completely beta reduces the given location.
This also exists as a `conv`-mode tactic.

This means that whenever there is an applied lambda expression such as
`(fun x => f x) y` then the argument is substituted into the lambda expression
yielding an expression such as `f y`.
