Though I tend to agree, and though it may not apply here, I'd like to
try to make sure we all consider whether or not the way guile has
handled things up to now may have hidden a bunch of operations that
are more or less equivalent to using eval. In such cases (personally
speaking) I'd probably rather just see an explicit eval.

I'm not sure -- it might be nice if the guile interpreter was smart
enough to detect and handle such things if the costs (in code,
performance, and time complexity) aren't too high when running
interactively.
However, I'd like to try not to require things of *non-interactive*
sessions that are at odds with extremely efficient offline
compilation, a situation where separating the expansion environment
from the evaluation environment is likely to be fairly important to
good performance.
