Okay, I'm going to abandon this branch for a bit. My #PureScript tests seem to be causing my dependencies to fail, without (obviously) calling my code:
```
file:///home/bss/git/halogen-lambda/output/Test.QuickCheck.Gen/index.js:149
var f = function (s) {
^
RangeError: Maximum call stack size exceeded

```
BTW, anyone know how to apply a source map to a #nodejs backtrace?
