If the new compiler/translator framework in Guile 1.9.x is capable of
handling ECMAScript and elisp, it should certainly (in principle) be
able to handle slightly different variants of Guile Scheme.  So that
might be a good way of handling any recasting at runtime.  I believe it
also supports writing out recast code - although perhaps at the cost of
losing some formatting and comments.

Can you give an example of what grok-db might say?

Also note that grok-db is in a sense already present, in the source code
of the compiler.
