this'd be cool. might also be nice to have a variant that does the utf-8 pre-processing at compile time and yields a str. |

Yeah. Could also construct a few literal/constant types. Would also be interesting to have an #include that actually feeds the input through the parser, rather than yielding a specific literal. Maybe that's too subject to abuse though? |

@paulstansifer I believe this is done. Can you confirm? |

For testing purposes I've frequently wanted to do something like:
It would read a file relative to the directory of the current source file (not sure what it would do when building stdin - probably relative to cwd).
I think nmatsakis mentioned that D can do something like this. Let's copy it.
