in reply to do/redo or for(;;): what's Kosher?

For infinite loops I like

while(1>0)
{
  # do stuff
}

This makes it really obvious that I mean 'forever'. Some of my co-workers have said that it really jumps out at them.

It should work perfectly the first time! - toma

Personally, I just omit the condition all together:

while()
{
...
}

Not sure why it works, but it does.

This is why it works:

2;0 juerd@ouranos:~$ perl -MO=Deparse -e'while () { print "1\n" }'
for (;;) {
    print "1\n";
}
-e syntax OK



Many people aren't going to like this:

2;0 juerd@ouranos:~$ perl -MO=Deparse -e'while (1) { print "1\n" }'
for (;;) {
    print "1\n";
}
-e syntax OK





2;0 juerd@ouranos:~$ perl -e'undef christmas'
Segmentation fault
2;139 juerd@ouranos:~$

Along similar lines, I sometimes use

  until (2 + 2 == 5) {
      ...
  }

which evokes eternity beautifully, in my mind.

Reminds me of a friend of mine (Hendrix fan), who always uses

  if (6==9)

as a break condition. Very cool, IMO.
