The function Trace markes a function to be traced
so that it will be evaluated step-by-step when called.
Arguments
- FUN
the function to be traced.
Details
Trace differs
in semantics from the function trace which
allows to insert expressions at given positions within a function.
Nevertheless, it uses the function trace internally.
Therefore the effect of Trace(FUN) can be undone by the call
unrace(FUN)
