It's a general feature of perl, not specific to Catalyst.
As your most probably already know, when you say::
use Some::Module qw(some thing);
it behaves as if you had written::
BEGIN {
require Some::Module;
if (Some::Module->can('import')) {
Some::Module->import(qw(some thing));
}
}
When you write::
use Some::Module 1.3;
it behaves something like::
BEGIN {
require Some::Module;
Some::Module->VERSION(1.3);
}
The ``UNIVERSAL::VERSION`` method throws an exception if (in this
case) the ``$Some::Module::VERSION`` variable has a value less than
what was passed (``1.3``). So you're essentially saying "use this
module, at least this version, or die".
