There's a bug in the ticket -- if(a != null) a = b; should be if(a == null) a = b;

Of the two options:

#Issue #1216 with pull #1348#

##Issue## As @satyr pointed out, the #1216 patch (pull #1348) broke some ?=:

Debug mode for running .coffee scripts #558, #987

Adds a --debug option for .coffee scripts that outputs more helpful error messages (mapping compiled .js lines of code to the input .coffee file's lines).

This branch should be considered experimental at the moment -- it serves as a proof-of-concept and to expose additional issues with adding debugging support to CoffeeScript

Current output:

TypeError: string is not a function
