+# Inline `dyn`
+
+A relatively simple example wrapper working (kinda) as a *by-value* `dyn Trait`.
+
+Limitations:
+* The wrapper size is fixed. The content either fits, or it doesn’t compile.
+* Supporting each trait requires a bit of code, as there is no way to express “for each *trait* X” in Rust.
+* Requires unstable features (notably `ptr_metadata`, others are probably avoidable).
+* `unsafe` here, `unsafe` there, `unsafe` everywhere! (It does pass Miri though).
