+This has given us a REPL where we can call parsing functions. There's a convenient `debugParseScript` function that will take a string and give the complete parser result (minus noisy token positions):

-Not very pretty, but we can see the part we're interested in:
+Alternatively, if we've looked at the unit tests and found the parser responsible for a syntax element, we can use `debugParse` to call it directly:
+
+```haskell
+*ShellCheck.Parser> debugParse readIoRedirect  "> tmp"
+Right (T_FdRedirect (Id 0) "" (T_IoFile (Id 1) (T_Greater (Id 2)) (T_NormalWord (Id 3) [T_Literal (Id 4) "tmp"])))
+```
+
+Neither is very pretty, but we can see the part we're interested in:
 
 ```haskell
 (T_IoFile (Id 11) (T_Greater (Id 12)) (T_NormalWord (Id 13) [T_Literal (Id 14) "tmp"]))
