An EX$Val has the following concise methods for checking the type of its wrapped '$$' value: isR (for Real); isI (for Integer); isB (for "Boolean" True|False); isS (for String); and isQ (for Quantity).

These may be used in ADT "constructor" type checks (which can leverage the Wolfram Language MatchQ and the Devel` package functions checkFatalArgs and failedArgsHeads).
