What's so bad about context dependent keywords?  They're great for 
disambiguating confusing syntax and making it more readable:

alias 'type' as 'identitifer'

Now you know the order of the alias statement; it reads left to right. 
You don't have to force 'as' to be a real keyword and effectively 
disallow its use as a variable.
