Fatal flaw in D design which is holding back widespread adoption

In Python3+ if you mix tabs and spaces to indent code, the "interpreter" raises a parsing error. So you are forced to use only tabs or only spaces to indent code. Only really newbies mix tabs and spaces in Python 2.x code.

And the Python coding standards (PEP8, http://www.python.org/dev/peps/pep-0008/ ) says:
"Use 4 spaces per indentation level."
And all a little serious Python programmers follow it.
