+## Brace expansions and globs are literal in assignments. Quote it or use an array.
+
+### Problematic code:
+
+    foo={1..9}
+    echo $foo
+
+### Correct code:
+
+    foo=( {1..9} )
+    echo "${foo[@]}"
+
+### Rationale:
+
+`echo *.png {1..9}` expands to all png files and numbers from 1 to 9, but `var=*.png` or `var={1..9}` will just assign the literal strings `'*.png'` and `'{1..9}'`. 
+
+To make the variable contain all png files or 1 through 9, use an array as demonstrated. 
+
+If you intended to assign these values as literals, quote them (e.g. `var="*.png"`).
+
+### Contraindications
+
+None.
