I want to convert between various integral types; for example Word32 and Word8.
What is the idiomatic way to do this in Haskell?
Word8 -> Word32 conversion can always succeed. Word32 -> Word8 conversion might result in an overflow and I'll deal with that (either by testing explicitly or getting an indication from whatever the conversion idiom is).

In computer programming, a programming idiom or code idiom is a group of code fragments sharing an equivalent semantic role, which recurs frequently across software projects often expressing a special feature of a recurring construct in one or more programming languages or libraries.

In implicit C++ type casting, the data type in which the value is to be converted is not specified in the program. It is automatically done by the C++ compiler. When constant values and variables of different types are mixed in an expression, they are converted into the same type.
fromIntegral will convert from an integral type to any numeric type, including other integral types
