+- The compiler now performs function inlining optimisations for a specific set
+  of standard library functions, which can allow functions which were previously
+  not tail-recursive on the JavaScript target to become tail-recursive. For
+  example, the following code:
+
+  ```gleam
+  pub fn count(from: Int, to: Int) -> Int {
+    use <- bool.guard(when: from >= to, return: from)
+    io.println(int.to_string())
+    count(from + 1, to)
+  }
+  ```
+
+  Would previously cause a stack overflow on the JavaScript target for large
+  value. Now it is rewritten to:
+
+  ```gleam
+  pub fn count(from: Int, to: Int) -> Int {
+    case from >= to {
+      True -> from
+      False -> {
+        io.println(int.to_string())
+        count(from + 1, to)
+      }
+    }
+  }
+  ```
+
+  Which allows tail-call optimisation to occur.
