Printing values

Printing values

[Christian Stork]

This must be a dumb question, but I couldn't find an answer.

How can I print values of my own data types in the default way, eg, as
the debugger or the toplevel does it?  Is there a standard formatter
that I can use (or generate), or do I have to write a new formatter for
each data type? 

Thanks,
Chris

One solution is to use Std.dump in Extlib[1].  It's not (AFAIAA)
available in any released version of Extlib, so you'd have to use the
CVS version, or use the original standalone version from which it is
derived:
