pipe dreams Juerd wondered if he could mix = and ==> in a sane way. The answer appears to be no. Once you bring in ==> you should stick with it.
Huh?!? It doesn't seem to me that the answer is 'no'. In fact C<< ==> >> is supposed to be yet another operator, albeit somewhat a special one. If I got it right the answer is actually 'yes': what Larry suggested is that it would be _stylistically_ better to stick with it once it is used in the first place.
It was also a matter of precedence, as = binds more tightly than ==> so extra brackets would be required, leading to ==> being neater if you only use it in conjunction with other ==>. Which I rather liked.
