I didn't know that. Thank you.

Yes, it works.

Not exactly. The { , } construct is somewhat different than ( | ) :
for example, when one of the partterns fails, the whole expression
fails.

Like :

% echo (foo*|bar*)
foo
% echo {foo*,bar*}
zsh: no matches found: bar*

The { , } construct always expands its components : echo {foo*,bar*}
is exatcly the same as : echo foo* bar*

That's why I prefer ( | ) in general ofr globbing.
