On: Can a language have Lisp's powerful macros without the parentheses?

Could you give an example that's more powerful? From the 60-second intro you linked to, these look no more powerful than C's macros.

I don't use it myself; I just had it in my bookmarks.

I am also not very familiar with Lisp's macros. You may find something of interest in the more complete documentation.

Sorry.
