in reply to Should loop {} really loop indefinitely?

The infinite loop is in fact very useful, and I had to explicitly tell my optimizing C compiler (back in the day) not to replace it with a nop instruction when in fact the loop was waiting for an interrupt to occur from an I/O port.

With that perspective, I think the code should in fact just loop there forever. You presumably wrote it that way for a reason. :)

On time, cheap, compliant with final specs. Pick two.

    In Perl 6, when you want to idle indefinitely, you should probably write:


    Also, as mentioned above, replacing loop {} by a nop would be just as false as letting it loop forever. 0 * Inf is neither 0 nor Inf.
