Utility to trace your traversals by passing your traversal function to this trace_wrapper

t_simple_filter_fn()

t_simple_filter_fn() :: (any() -> boolean())

t_simple_mapper_fn()

t_simple_mapper_fn() :: (any() -> any())

t_simple_walker_fn()

t_simple_walker_fn() :: (any(), any() -> any())

t_traceable_fn()

t_traceable_fn() ::
  (any() -> any())
  | (any(), any() -> any())
  | (any(), any(), any() -> any())

make_trace_fn(fun)

make_trace_fn(t_traceable_fn()) :: t_traceable_fn()

Utility to trace your traversals by passing your traversal function to this trace_wrapper.

Instead of passing f you can pass make_trace_fn(f) as long as f is of the correct type.

This wrapper will trace the actual arguments and the return value to stderr.
