Doesn't exactly say whether "use strict" is better or not, though.
If it is generally regarded as better, perhaps "use strict" should be
the default with "no strict" to override it if necessary (ever?)

That would break many existing programs.

That would be not nice at all!



Have you seen the BUGS section in "perldoc perl"?

(-w (similar to "use warnings") being off by default is a known "bug")

better than what?

Oh.

Then you want the 2nd paragraph of

perldoc perlstyle

... You should also always run under C<use strict> or know the
reason why not.

Since Robin (and, I assume, you) do not know why you would _not_ use strict,
you _should_ use strict. :-)

Then it might be better to know circumstances one wouldn't use strict in
relation to vars, subs, refs, performance, debug, production, bugs, versions,
etc ... There has to be a starting point for full understanding.

Decades of non-perl programming shows me plenty of reason to "use
strict" in my own perl code. Tad is right that I really don't see the
reason ever not to, but I suppose I'll see it when or if I ever run into
it.

As for breaking existing code, some of that breakage probably uncovers
existing bugs. If it breaks, it's not following perlstyle
recommendations anyway.
