+# Solutions
+
+Currently solutions are only provided in a non-human-readable form in the page source.
+Those are mostly inteded for testing that the exercise is even possible to solve.
+```rust
+# /*
+fn fix_me() {  // Greyed out because the solution changes this line.
+# */
+# fn fixed_name() {
+}
+
+fn do_not_change_this() {
+    fixed_name()
+}
+```
+Some exercises may not include have the replaced parts greyed out:
+```rust
+# mod __ {
+fn fix_me() {
+# }
+# mod }
+# fn fixed_name() {
+}
+
+fn do_not_change_this() {
+    fixed_name()
+}
