Fair enough. But when designing such an application, it helps to know
what might be in the Lindasphere.

No, not at all. Statute interpretation is not the *primary* function of
judges (which is to make judgements in "actual case[s] or controvers[ies]",
as the U.S. Constitution says), but it is a function. When interpreting
a statute, the judge attempts to understand what it means, but "what it
means" is not always plain on the face of the statute, so appeals to
Congressional intent as shown in the record of how the statute was passed
are common.

Every application must respect some constraints, otherwise it would be
able to do everything with anything.
