That is a thing of beauty.

As promised, glls now supports the (optional) automatic generation of
functions for rendering pipelines. This function generation manifests
differently depending on whether your file is compiled or evaluated. When
compiled, rendering functions are compiled to efficient C. When evaluated,
a generic (not remotely efficient) rendering function is used.
glls also now provides support for dynamic reevaluating of pipelines in
such a way that the old program object ID is reused, so that your scene is
instantly updated.
Two new examples were added (texture.scm and interactive.scm) to
illustrate these new features:

And, of course, the documentation describes these changes in detail:

glls is now a rather unique library for shader creation. Not only does it
provide far tighter integration into the host language than the usual
method for working with shaders, but it also makes few to zero speed
sacrifices (when compared to hand-written C) even when the automatically
generated rendering functions are used. These features were very much born
out of Chicken’s unique strengths – I really can’t imagine combining them
in any other language or even Scheme implementation. A big thanks to the
Chicken team for creating a language and environment where this sort of
thing is possible!
