Additional context
Add any other context about the problem here.

• OpenSCAD Version: 2015.03-2, Windows 10 (wow, this is a truly ancient version of OpenSCAD...)
• Other libraries used: None

It works perfectly with OpenSCAD 2021.01 (and most probably does with 2019.05).
Is there a special reason for using such an old version of OpenSCAD?

[watching-spd]

No, there's no good reason! I just didn't realize until cutting this issue how out of date I'd let it get. :)

I've got a work-around (commenting out that module), but it might be nice to find the minimum supported version and throw a more useful error message in the case where the library uses newer language features?

[fe60]

The error message is thrown by OpenSCAD. So there is nothing the library can do about it. And I'm not sure how OpenSCAD could handle this in a better way. It stumbles across an unknown statement and fails with "Syntax error". It can't know, it's a valid language feature in future versions.

I forked the git repository behind the wiki into a new one and started adding fixes. Its README declares OpenSCAD 2019.05 as minimum version.
Once I think it is a feasible approach to host the documentation in a separate repository, I will ask the owner/author of BOSL to move the wiki into a dedicated Github-Repo to allow wiki contributions from everyone.

BOSL v1 wiki is now publicly editable.

I recoded stagger_sphere() to avoid using each. It works with OpenSCAD 2015.03 now.
