Suppose you have the code:

 if a = 1 and foo(bar) = 3 then
   do something

Supposing a did not equal 1,
then Euphoria would not bother to look at foo(), so foo() would not be
executed.
Sometimes you might be expecting foo() to do some work besides just
returning
a value to compare, and in this case, that work wouldn't get done.
Hence the warning.
