When called with no arguments, it returns the symbols of all functions currently being traced. When called with one or more functions as arguments,
returns a list of the symbols of those functions. Thus, in all situations,
returns a list of the symbols of those functions being untraced.
is used to cease the tracing of functions. If it is called with no arguments then the tracing of all currently traced functions is stopped. If it is called with one or more symbols then the tracing of those functions is stopped. A warning is given if
is called with a function that is not being traced.
