<div>Hi all.</div>
<div>I study Mercury language now wich I consider as trusted Prolog. In the prolog it is possible to introduce own operations with given priorities. I have a question: Is it possible in the Mercury language to define own logical operations: and, or, xor, <=>, <=, =>? Seems "or" frequantly used in the Mercury programs instead of "xor" wich can result in the program failures. It is more beautifully to write "and" instead of "," and "or" instead of ";".<br clear="all">
