    About static typing and generic functions, are there limitations to fast-generic-functions built over sealable-metaobjects too? I felt that reasonable, albeit it takes away the dynamic nature of the objects after sealing.

    There is significant overlap with SICL and its associated pieces which supply many of the other parts needed to make a Common Lisp. Some of these are Cluster which provides a portable and extensible assembler, Eclector which supplies a portable and extensible reader, Concrete-Syntax-Tree that supports source code tracking during compilation, ctype that implements the Common Lisp type system, and Clostrum that provides first-class environments for e.g. run-time, evaluation, and compilation. The SICL project has as one of its goals the creation of portable infrastructure for implementing Common Lisp, and these pieces are novel building blocks that were created as part of the project.

    Other times, the support is limited by the implementations supported by ctype and cl-form-types (and cl-environments). Although, if there is any good request, I could work on making a dynamic-only ANSI-CL compliant sub-system of PF.
