Sure. Just be kind to yourself, and have barf() return a meaningful value, such
as, in this case, an explicit undef or 0. Have the outer sub return a true value
if the nauseous condition does not occur. That way, the caller of the outer sub
can read a true return value if it doesn't barf. Very useful for error-trapping.
