Re: Subroutine Time::HiRes::Time redefined ... Help

Which version of Time::HiRes are you using? Which version of perl? Which versions of all the other modules?

I don't have POE::Component::DirWatch::Object installed here, but taking that out it runs cleanly for me.

For the record, it's considered better practice to do

#!/usr/bin/perl
use warnings;
[download]

in preference to

#!/usr/bin/perl -w
[download]

I thought along that same line of thinking and upgraded Time::HiRes, no help. But, It seems use warnings; Did it! Errors are gone. It seemed a more stylistic choice, but it fixed it. Can you explain? Sweetblood	[reply]

Basically, the `-w` flag is an all-or-nothing construct. It enables warnings everywhere in your code, including in the modules you use and you haven't written yourself. The `use warnings;` pragma, by contrast, is lexically scoped, so it does not overlap on other pieces of code used in your program. And you can turn it on or off for some chunks of code or for some specific warnings categories. I basically use the `-w` flag only for one-liners. The `use warnings;` pragma is much better for all other cases. See https://perldoc.perl.org/warnings.html#What's-wrong-with--w-and-%24%5eW for more details.	[reply] [d/l] [select]
