This module provides access to tracing functions from the pre-2003 Hugs trace module. Over time, it may accumulate other tracing functions that I find useful.
This should probably just be replaced by Debug.Trace.
Documentation
When called, trace
outputs the string in its first argument, before
returning the second argument as its result. The trace
function is not
referentially transparent, and should only be used for debugging, or for
monitoring execution. Some implementations of trace
may decorate the string
that's output to indicate that you're tracing. The function is implemented on
top of putTraceMsg
.
