Brace expansion is essentially separate from the rest of the expansions:
in fact, it's designed to be part of a separate library if desired. As
such, it doesn't implement all o

Brace expansion happens before parameter expansion (man bash,
EXPANSION). So the first "}" ends the parameter expression, and the
second "}" isn't special. The result of param

i'm pretty sure the commas are consumed in the expansion
side note, this also fails:
