I'm actually thinking about writing a D pretty printer as a little
exercise in D programming. I haven't decided whether or not to simply
adapt the existing dmd frontend. One of Walter's stated advantages of D
is that it's easily lexed and parsed, even if semantics are disregarded.
I'm considering to prove that statement by building a lexer/parser from
ground up, though of course lacking most of the complexity of the real
compiler since I only need to do just enough to be able to pretty-print
If it's done correctly, it might even be useful in automated conversions
between different preferred indentation styles, etc..
This is a tpyo.
