Resist the urge to use lazy lists

For day-to-day small dataset conversions, it is probably best to use
strict lists in Scheme.  Lazy lists need some machinery to work well
in Scheme; and it complicates programs.

So, note to self: don't use streams unless the data sets are really
large.  PLT scheme's list comprehensions are probably simpler to use.
