{{draft task|Type detection}}
This draft task needs a purpose, a description and some way to tell whether examples satisfy or do not satisfy it.
;Task:
Show a function/procedure that processes a block of text by printing it.
The function takes one parameter (ideally) that describes the text.
Demonstrate by calling the function twice, each time passing in a different type.
This can be done with pattern matching, multi-methods, dynamic type detection, structure(s) with a tag, etc.
The objective is write a [e.g. library] function that processes text from multiple sources (such as a string/char *, socket, file, etc).
If not practical, show how the caller would coerce a type that can be passed to the library function.
