I tried loading the file from github on emacs master and it fails when
trying to compile
```
(defun breadcrumbs--drop ()
"Track the buffer position as a `breadcrumbs--breadcrumb'.
If this has already been tracked, move an existing one in `breadcrumbs-ring' to head."
(let* ((breadcrumb (make-breadcrumbs--breadcrumb))
(index (ring-member breadcrumbs-ring breadcrumb)))
```
with
```
Debugger entered--Lisp error: (wrong-type-argument stringp (buffer-file-name))
make-breadcrumbs--breadcrumb--cmacro((make-breadcrumbs--breadcrumb))
apply(make-breadcrumbs--breadcrumb--cmacro (make-breadcrumbs--breadcrumb) nil)
macroexp--compiler-macro(make-breadcrumbs--breadcrumb--cmacro (make-breadcrumbs--breadcrumb))
```
The cl-defstruct slot has an initform "(buffer-file-name)" which seems
legit since it takes an optional argument.
However when I change the form to (buffer-file-name nil) as below, it
loads
```
(cl-defstruct breadcrumbs--breadcrumb
(buffer-file-name
(buffer-file-name nil)
:documentation "The file backing the breadcrumb.")
```
Common Lisp has a problem with the interpretation of the lexical
scoping of the initforms. C-h f cl-defstruct doesn't impose any
conditions on the SDEFAULT form. Are there any guarantees or
limitations on the forms that can go into SDEFAULT
