Python/Unix Hybrid Demoed at PyCon (xon.sh)
A new shell "combines the Python language with features of Bash Unix and the fish and zsh shells," according to InfoWorld. An anonymous reader writes: Pronounced "conch," but spelled Xonsh, it runs on Linux, Windows, and Mac OS X systems, bringing Python libraries to the command line -- for example, the ability to use regular expressions when globbing files. "The first thing you'll notice about Xonsh is that it's really meant to be used as a general-purpose shell," the lead developer explained in a presentation at PyCon. "But on the other hand, it really is Python, so you can do things like add two numbers together."
They're describing it as "a Python-ish, BASHwards-looking shell language and command prompt...a superset of Python 3.4+ with additional support for the best parts of shells that you are used to, such as Bash, zsh, fish, and IPython...the superglue that bonds Python to a command-line interface and other shells."

Why is the title of this article "Python/Unix Hybrid Demoed at PyCon" when it is a Python/Bash hybrid? Bash != Unix
Unix is not a shell (if it were, we would not need shells) and Xonsh/bash/Python are not operating systems.
Like PEP 8 clearly says,
Use 4 spaces per indentation level.
That's it. That's all there is to it. It's simpler and clearer than the rules for just about every other programming language out there.
Anyone who can't handle using 4 spaces is a lost cause.
They clearly define the block no matter how you format it.
More than once I've seen a python program where someone has accidentaly deleted tabbed whitespace on a end line in a block and moved that line into the outer block and of course python says nothing. But now the program is broken. Try removing a bracket in C/C++/java and see what happens.
Whitespace as a block delimiter is a retarded idea, always has been, always will be.
