It's just so I didn't have to escape the quotes :D

Otherwise it looks like this:

return "writefln(\"mode " ~ mode ~ ": %s\", " ~ value ~ ");"

I think we can probably do a compile-time substitution processor like 
rust (and other languages, including php and ruby) which just uses the 
variable name inside a string with some escape around it. `~var~` is not 
very succinct, I like $var better.
