What is the correct way to unify the types of two operands of a binary
operator? The specs talk here and there a little bit about rules for implicit
conversions, but that doesn't really tell me much about how to implement this
stuff in my own compiler.

I'd love to have a detailed guide for how to actually do semantic analysis in a
D compiler. There really need to be documents that explain the D language with
actual compiler writers in mind. I have seen such a thing for Java some time
ago on the web. I would've given a link, but I don't remember anymore where I
saw it.
Perhaps somebody, who knows the front-end well, could help you out on typing up
these kind of documents? A sort of collaborative project using a wiki system?

Most of the time I simply have no clue what to do, SA is darn complex. :(
