# NOTE: There is currently no way to influence the return
# code of SciTECO, except to provoke an error.
# Since errors cannot be yielded explicitly, we use the
# idiom "(0/0)" to enforce a "Division by zero" error
# whenever we want to fail.
#
# NOTE: Square brackets are significant for M4 but
# often required in TECO code as well.
# We therefore use double brackets [[ ... ]]
# (translated to [ ... ]) in simple cases where balanced
# brackets are required in TECO code as well and
# quadrigraphs (@<:@ and @:>@) in all other cases.
