 ```kcl

 Keyword arguments help keep your KCL programs readable, and allows us to add new features to the standard library in a backwards-compatible way. Suppose that KittyCAD releases KCL 1.4, which adds a new positional argument to a standard library function `sphere`. Any programs using the definition of `sphere` from KCL 1.3 would stop compiling when you upgrade to 1.4 (because they're missing a parameter to `sphere`). But if we add the new parameter as a _keyword parameter_, your existing programs will keep working -- they'll just use the default value for that parameter.
