See section 12.6.3 in the MzScheme manual for an explanation of
certificates.

If you're writing a program-processing tool, you'll need to recertify
expressions that you assemble from pieces of pulled-apart expressions.
Or, if you don't care about discarding the enforcement power of
certificates, you can just recertify every expression as soon as you
extract it from an enclosing expression.
