Yes, that sounds reasonable.

In terms of usability you want to catch typos so you want some 
redundancy, but I don't know whether this is a likely typo.

But in general, it is possible to construct a language where all 
strings are valid programs. That would also mean that all typos 
would go un-noticed in that language.
