Why not?

Here's one reason:

cmpthese -1, { a=>q[ open O, '>', 'log'; for(1..10000){ print O chr(0)x80; } close O; ], b=>q[ for(1..10000){ open O, '>>','log'; print O chr(0)x80; close O; } ] };; (warning: too few iterations for a reliable count) s/iter b a b 1.30 -- -99% a 8.42e-003 15300% --

A second reason is that the first consumes almost no resource; whereas the second consumes prodigious amounts of it.

The times before and after the first:

a 5.546|5.343|0|0 a 5.546|5.343|0|0

And the second:

b 5.578|5.343|0|0 b 5.734|6.375|0|0

Whether you are just impacting every other process on your local server; or being billed for all that addition CPU & IO when running your process in the cloud; incurring 1000's of times more resource use in order to satisfy a dumb tool that is easily silenced is .... Its your dollar, you pick the adjective.

In the absence of evidence, opinion is indistinguishable from prejudice.

[marinersk]: I've often marvelled over the past few decades at just how little it takes to mess me up with this spacial dependence thing. I wonder if I'm mildly autistic or something.
