I think it is more of a case of unrestriced parameters
and undefined limits. The problem is finding the pesudo-constants used
in a program and modifing how we think about program design. Say you
have parsing routing that say "speaks your files selected". What happens
if you save a email from a friend who speaks Japanese? Can the program
be modifed from a config file or is it hard coded? What hapens if you
have Windows 2040 with unlimited length file names? True people
make mistakes but software design works best only you have written it
a few times from scratch. :(
