We're long overdue for a "D is awesome" post

Excellent! The technique you're exhibiting is called "mocking". It works 
especially well when a function's inputs and outputs are properly parameterized.

When I fixed the D lexer.d to not access any globals, I was able to simplify the 
unittests for it by mocking up the inputs and outputs. For example, instead of 
having to use the global "gagging" switch to suppress error messages, I used a 
mock error handler that just did nothing.
