+## Quote this invalid brace expansion since it should be passed literally to eval
+
+### Problematic code:
+
+```sh
+eval echo {1..$n}
+```
+
+### Correct code:
+
+```sh
+eval "echo {1..$n}"
+```
+### Rationale:
+
+Using `eval somecommand {1..$n}` depends both on bash silently failing to interpret the brace expansion, and on it passing failing brace expansions literally. 
+
+Rather than depending on these questionable features (which already behave differently in other shells), use the explicit, predictable way of passing values literally: quoting.
+
+### Exceptions:
+
+None.
