Re: use Ispecific/I version

in reply to use _specific_ version

I believe you're looking for 'require'.
At the top of your code put a line 'require 5.006;' or similar.
As far as I'm aware, it just forces the compliance with a particular, known and tested version of Perl.
Is it a requisite that it needs to check for more than one version of Perl, or just require the one?
You could use the $] (perl version variable) as a trap, but, on the whole, I think requiring a particular version is cleaner.

    no, no.

    require and use both specify this version or higher. the difference between require and use is that require is executed at runtime, and use is executed at compile time. therefore, if i require 5.6.0, any BEGIN blocks will execute before the version of perl is checked.

    that would be a Bad Thing.
