Sample not quite working?

[tedneward]

I do the sample from the README:

var contracts = require("contracts-js");
setupContracts(contracts);

fun (Num) -> Num
function dbl(x) { return x + x; }

console.log(dbl(4));

But when I run, it fails because "npm install sweet-contracts" doesn't seem to have "contracts-js" as a dependency. No worries; I "npm install contracts-js" and that works fine--it's installed. When I "sweet-contract" the source above, no errors. But when I run, I get "ReferenceError: C is not defined"; the output file looks like this:

var contracts$0 = require('contracts-js');
var C$2 = contracts$0;
var dbl$5 = C.guard(C.fun([C.Num], C.Num), function (x$8) {
return x$8 + x$8;
});
console.log(dbl$5(4));

Sure enough, if I manually edit the output to change "C$2" to "C", it works great. It looks like C is getting picked up by another macro and transformed.

Is this a known issue, am I doing this wrong, or am I misunderstanding things here?
