Well 'type-bondage' is a strange way of thinking about compile time type 
checking and making code easier to read (and therefor debug) but
I'm not about to get into some religious war about declaring a variables 
type. I'll just say that I prefer to devote testing efforts to the real 
danger area which in my experience is 'user' input.
Clients look dimly on runtime errors however they occur and if I can 
leave it to the compiler to check as much as possible then I'll take that.

I do understand however that compiling an intepreted language doesn't 
really make sense however i'm sure there are interpreted languages that 
allow pre-execution type checking ... aren't there ? Oh yes, there's one 
called Java :-)

Still, I'm sure you're only kidding around with me :-)
