Description

Prints object to stream.

Methods for this function should print objects as a message, as opposed to printing them in any form intending to represent Dylan data, literal syntax, and so on.

For example, printing a condition object with this function presents the condition as an error message, but printing the condition object with the print function from the Print module prints the condition in some form such as

  {Simple-error}

See the individual methods for the details of how this function prints various objects. This function exists to define the behavior of the %S format directive and to allow users the ability to extend the %S directive. Users should have little need to call this function directly.
