+## Did you mean IFS=$'\t' ?
+
+### Problematic code:
+
+    IFS="\t"
+
+### Correct code:
+
+    IFS=$'\t'
+
+### Rationale:
+
+`IFS="\t"` splits on backslash and the letter "t". `IFS=$'\t'` splits on tab.
+
+### Contraindications
+
+It's extremely rare to want to split on the letter "n" or "t", rather than linefeed or tab.
