Enabling a Handler While Within a Function (in function)

To enable a handler while within a function, type:

<dbx> trace step -in foo

This is equivalent to:

    # create handler in disabled state
    when step -disable { echo Stepped to $line; }
    t=$newhandlerid    # remember handler id
    when in foo {
     # when entered foo enable the trace
     handler -enable "$t"
     # arrange so that upon returning from foo,
     # the trace is disabled.
     when returns { handler -disable "$t"; };
