They are, therefore identifiers couldn't start or end with a dollar in any
case. However, single "$" operator cannot exist, so foo$bar wouldn't be
ambiguous, but the tendency to confuse it with an operator syntax would
reduce the readability of code greatly, IMO. However, a $$ operator can
exist, so a construct like foo$$bar would parse completely differently,
leaving you with a big mess.
