I was delighted to learn that @ used to have a companion symbol, a script r with a tail that also went around it in a partial circle - it was used as a currency symbol for the Reis... but although Brazil has brought back the Reis in place of the Cruziero, they no longer use that symbol.

One way to avoid the inconvenient need for completely new symbols... is to avoid discarding old ones.

Thus, I once designed the definition of a computer language in which a complex number could be specified as X + !Y, and the upside-down ! and ? from Spanish were used as unary operators to multiply numbers by j and k to form quaternions...
