In general, the interactive spec should only read the arguments.
The "real work" should be done in the function body once it gets the
arguments.

The reason for this is clean design, and to gives the right
relationship between interactive calls and noninteractive.

However, reading the arguments can legitimately have side effects,
byproducts of reading the arguments -- for instance, changing the
obarray if you need to intern something.
