Well, they would be if filenames were always just a long string of
characters.  Under Unix and AmigaDOS, filenames are not composed of
various "fields" such as filename, extension, and revision number
(ala VMesS).  Unix file names are simply strings (length limited by
the OS filesystem) of eight-bit bytes.  Any sort of "extensions"
(e.g. .c, .o, .f, and .s) are either generally accepted conventions or
desired by not-so-liberal compilers.  Thusly, "visual separators"
such as a period are no more different in a filename than the letter
A or the number 6.

Under ugly and awkward beasts [for me anyhow] such as VMesS and
MesS-DOS filename are composed of fields enforced by the file system
or O/S.  VMesS has filenames broken up into fields and the wildcards
only apply to a given field.  The period (and VMesS's semicolon) are
not "really" quite part of the filename (at least not how I look at
them). 

If I remember right, under IBM's VM file names have three parts also;
a filename, extension, and disk letter(?).  As best I can remember,
file specifications used whitespace to separate the fields (and not
periods).

And does anyone remember TRS-DOS??  :-} Didn't it use slashes (/) to
separate filename and extension? 

Oh well, back to my cage....
