 ### Fixed
  * Fix a bug where `basilisp.lang.compiler.exception.CompilerException` would nearly always suppress line information in it's `data` map (#845)
  * Fix a bug where the function returned by `partial` retained the meta, arities, and `with_meta` method of the wrapped function rather than creating new ones (#847)
+ * Fix a bug where exceptions arising while reading reader conditional forms did not include line and column information (#854)
