[Catalyst] strict stash vars

[Ruslan Bondarev]

Hi.
I wonder if there is a stricter stash plugin to store vars?
I mean stash that knows what exactly variables have been created, 
so if I make a typo in my template file, it will croak about invalid var.
Also, I can easily overwrite someone's (plugin?) var, because 
of free form "namespace", and this may break things and will be 
very hard to debug, imho.
Please advise.
