restriction
     
        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
        (especially 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.
