So does allowing strings to be any length.

Most of the time, I expect my strings to be short.  1000 characters is
good enough for most uses of strings, and when more is needed, a million
should do most of the time.

Granted, unlimited string length allows code to work for longer strings
than foreseen (as common sense states) but (if you're consistent) you
feel the potential for more undetected bugs outweighs this benefit.


By this parallel, I intend to communicate that (and part of why) I
consider your observations to be totally without merit.
