hushbugger 0.0.1

`hushbugger` is an alternative to a debugger. Instead of helping you find bugs and remove them, it will do its best to make bugs invisible.# ExampleImagine you have the following code (as featured in the [Hypothesis docs](https://hypothesis.readthedocs.io/en/latest/quickstart.html)):```pydef encode(input_string): count = 1 prev = '' lst = [] for character in input_string: if character != prev: if prev: entry = (prev, count) lst.append(entry) count = 1 prev = character else: count += 1 else: entry = (character, count) lst.append(entry) return lst```It has a fatal flaw: it crashes if you give it an empty string:```>>> encode('')Traceback (most recent call last): ...UnboundLocalError: local variable 'character' referenced before assignment```To hide the bug, simply apply the `hush` decorator:```pyfrom hushbugger import hush@hushdef encode(input_string): count = 1 prev = '' lst = [] for character in input_string: if character != prev: if prev: entry = (prev, count) lst.append(entry) count = 1 prev = character else: count += 1 else: entry = (character, count) lst.append(entry) return lst```Now it works!```>>> encode('')[]```# How it worksIf the function raises an exception, its bytecode is disassembled and inspected to look for return statements. If a constant value is returned (e.g. `return True`), that value is used. If a variable is returned (e.g. `return x`), and that variable had a value at the time of the exception, that value is used.If no usable return statements are found, a `Dummy` object is returned. It responds to almost any operation you throw at it (calling it, adding it, iterating over it, etcetera), so hopefully it gets discarded before visibly breaking anything. Its `repr` is also disguised, as if it belonged to a random module.```py@hushdef double(x): return 2 * x``````>>> double([1, 2, 3])[1, 2, 3, 1, 2, 3]>>> ret = double({})>>> ret<errno.Coalescer object at 0x7f96708cb438>>>> len(list(ret.invert()))51```# Installing```pip install hushbugger```
