Reuse 'do' keyword instead of hash sign (#)

[Brian Goetz]

Already considered!

Some problems:
  - It is already an identifier (meaning it suffers to some degree from 
the "new keyword" problem);
  - Most of the world doesn't know how to type it;
  - The name "lambda" doesn't mean anything to most developers, only to 
computer scientists.  So it won't look any less random that # or ^ or 
%#@($@(#$*, just harder to type.

That said, if IDEs wanted to offer the option to *display* it as λ 
instead of # or whatever other syntax is chosen, I'm all for that.
