shouldn't this just be ( break ) now? I believe the expression list was used as a return value to the label.

You're right there a bug here, but, because labels still return a value (this patches changes that from value list to value option) this should be (break <var> <expr>?).

Thanks for reviewing. I'm inclined to wait for @rossberg-chromium to return before merging, unless he was going to be offline for a while. Anyone know? |

Could you do the corresponding change in AstSemantics before merging? The idea sounds fine to me, I just want to make sure the more-oft-observed design repo gets a say in this! |

@jfbastien I was about to say that this PR simply implements what's already in |

This patch builds on #53 and implements imports of builtin functions as discussed in #47. The main difference is that, instead of injecting imports into the index space of functions (such that, after importing a function you call it with
(call ...), the patch creates a separate index space for imports that are called through a new(call_import ...). The reason for this is that I think it makes everything (codegen, spec, impl) simpler.
