ObserveFunction(args...; kwds...) = ObserveFunction(stdout, args... ; kwds...)

See @observe for details.

@observe func(args... ; kwds...)

Use Revise to "observe" changes to a functions behaviour. This will track the return values and the stdout/stderr of the function.

Notes:

• This only tracks stdout, stderr output using redirect_stdxxx. Many functions (e.g. display) will not output to the current stdout and so will not be captured.
• "Repeats" are recorded. Two calls repeat, when they have the same output.
• Currently, any change to the function's module will cause the function to be retested.
• This will probably only work on linux at the moment...
