You have removed and then changed the context to which
my statement applied.

The point is still very simple: braces are reserved
words.  They do get "interpreted", and the statement I
replied to incorrectly said they don't.

Your definition of "word" is parochial, and does not
necessarily apply to use of that term in a shell.  From
the bash man page:

 word   A sequence of characters considered as a single unit
        by the shell.  Also known as a token.

Clearly '{}' is a pair of tokens to the parsing engine.
In some contexts they each cause a "word break", and in
other contexts they do not.  When used to delimit a list
they do not cause a break and must be surrounded by
spaces.  When interpreted for expansion there is no need
for a space.

Brace expansion has not been standardized, but it is in
almost all major shells.  It needs to be understood by
a shell programmer.
