Pipes should work on everything! It also should be a PEP. For black.

[amogorkon]

Thank you so much for this brilliant little thing. I've just copy&pasted your main code as a tooling decorator into https://github.com/amogorkon/justuse and it does its job without complaining even once.
For example
ordered = releases >> _filter_by_platform(tags=get_supported()) >> _sort_releases

last_version = project.releases >> reversed >> iter >> next

meta = (names 
<< filter(DIST_PKG_INFO_REGEX.search) 
<< map(functions.read_entry) 
>> dict
)

Pipes make this so much nicer and less cluttered. Readability counts! I hope you will continue maintaining this beautiful thing and maybe even make a PEP for inclusion into the core language 👍

This probably is also the only way to fix a little issue that happens when you write a small chain of pipes like

a = (foo
>> bar
<< baz
)

which would look ugly on a single line a = foo >> bar << baz with those arrows piping in different directions - alas, black thinks so otherwise, so it turns the multi-line pipe into a single line.

PS: You really should update your examples on your README to python 3 print-as-a-function ;-)

def calc():
    print 1 >> add(2) >> times(3)  # prints 9

should be

def calc():
    1 >> add(2) >> times(3)  >> print # prints 9
