This prevents build problems with the official image on DockerHub. +- Improved `(scheme lazy)` to allow `force` and `make-promise` to accept an argument of any type. Improved representation of promises to more precisely differentiate them from other objects. +- Updated `(scheme lazy)` such that `force` will recursively force promises. +- Add type checking to record type accessor functions. We now raise an error if the passed object is of the wrong record type. +- Fix issues with expanding `cond-expand` expressions in libraries. Previously there would be issues with the expansion if the code needed to be within the context of a `begin`. +- Modified the reader to handle escaped intraline whitespace properly, per R7RS.
