<br></div>With a collection of a hundred module files or so, combined with multiple issues from the refactoring, one is in for an afternoon of recursive grepping etc.<br><div><div><div><br></div><div>Questions:<br><br></div>
<div>1) Is this currently a "deep" issue, in the sense of how module resolving and instantiation is performed, layered with Typed Racket's mode of implementation, layered with CM and Raco's build system that prevents a more informative error message?<br>
<br></div><div>Or<br></div><div><br></div><div>2) Is this just a simple a bug, in the sense of oops, just forgot to print the error message concerning the offending source module and line?<br><br></div><div>If its 2) I'll work on debugging for a fix. If 1) I'm just not going to be able to tunnel through raco -> cm -> tr -> module expansion to run this down, so I'll punt.<br>
