The following module was proposed for inclusion in the Module List:
modid: Carp::Ensure
DSLIP: adpfg
description: Ensure a value is of the expected type
userid: SMERTEN (Stefan Merten)
chapterid: 3 (Development_Support)

similar:
Usage
rationale:
I have been inspired by `Carp::Assert', looked for a similar notion
and came up with `ensure'. So I think `Carp::Ensure' would be a nice
name.
I guess ohers had the same problem as me: Are the values in my
program really of the type I'm expecting them to be? However, at
least to my knowledge there is no decent solution to this very
common problem. Well, there is `Usage' and I used it some years ago.
But it's a pain to use :-( . Ahm, there is a module called
`Carp::CheckArgs' in the module list, but it is not available as it
seems?
Anyway, after thinking a bit about a nice grammar for describing
types, I couldn't resist writing the module. Meanwhile it is rather
done.
Because this is such a common problem, I think it will be of value
for others, too.
