Re: Re: do/redo or for(;;): what's Kosher?

I know it's more code, but my favorite method for obvious loops looks like this:

$forever = 1; 
while ($forever) { ... }

That won't be optimized away, but a constant true value (not 0, "0", "" or undef) are. This means you can have less code and more efficiency, but still the clarity you like: `while ('forever'){ ... }` [download] Which is equivalent to `while (1) { ... }`, which is optimized to `for (;;) { ... }`. `2;0 juerd@ouranos:~$ perl -e'undef christmas' Segmentation fault 2;139 juerd@ouranos:~$` [download]	[reply] [d/l] [select]
