It is also makes things more painful than they need to be for syntax
highlighters. 'as' went through the "not really a keyword" path, and
it's a recipe for complexity in the code generation toolchain and
general quirkiness as things behave in unexpected ways.

We have a defined process for introducing new keywords (i.e.
__future__ imports) and the PEP doesn't adequately make the case for
why we shouldn't use it here.

Cheers,
Nick.
