     Type:  defect       |                Status:  new
 Priority:  major        |             Milestone:  5.0
Component:  scrutinizer  |               Version:  4.13.0
 Keywords:               |  Estimated difficulty:  hard
-------------------------+-------------------------------
 In `tests/syntax-tests.scm`, the following warning is produced:

 {{
 "  (syntax-tests.scm:412) in procedure call to `chicken.base#exit',
 expected argument #1 of type `fixnum' but was given an argument of type
 `false"'
 }}

 `exit` is a local variable (an exit procedure from a `loop` macro. Either
 hygiene is not properly handled here, or the scrutinizer mistakes a local
 binding of `exit` for the global one (`chicken.base#exit`).
