:restriction: n. A {bug} or design error that limits a program's
capabilities, and which is sufficiently egregious that nobody can
quite work up enough nerve to describe it as a {feature}. Often
used (esp. by {marketroid} types) to make it sound as though
some crippling bogosity had been intended by the designers all
along, or was forced upon them by arcane technical constraints of a
nature no mere user could possibly comprehend (these claims are
almost invariably false).

Old-time hacker Joseph M. Newcomer advises that whenever choosing a
quantifiable but arbitrary restriction, you should make it either a
power of 2 or a power of 2 minus 1. If you impose a limit of
17 items in a list, everyone will know it is a random number --- on
the other hand, a limit of 15 or 16 suggests some deep reason
(involving 0- or 1-based indexing in binary) and you will get less
{flamage} for it. Limits which are round numbers in base 10 are
always especially suspect.
