I'm afraid it was -- Hugs now uses the same Debug.Trace as everyone else,
and that module has no traceShow.  There are some other minor differences
with the old Hugs trace too: Debug.Trace.trace appends a newline and
sends its output to stderr.

There are a few cases like this in the Nov2003 release, where some
backwards compatibility is sacrificed for compatibility with the
hierarchical libraries shared with other implementations.  The
hierarchical library documentation is a more accurate reference on
the library interface than the Hugs manual, which was written some
time ago.  Similarly the User's Guide included with the distribution
is the up-to-date reference for many features of the interpreter,
though it's not as detailed as the old manual in many places.
