Sorry, not clear what you're saying. I was aruging that their be a flag that 
by default ignores the spec as written and implements the spec as "it ought 
to have been written". Until then spec is updated, MLton deviates from the 
spec in ways that are only "good". However, users who are concerned with 
absolute conformance can turn off strict checking.

In general, I would hope conformance to the spec, doesn't not prevent MLton 
developers and users to benefit from improvements until an offical revison 
comes out. I suspect many of the improvements will be adopted by other 
implementations.  So there is the defacto spec as any sensible developer 
ought to implement it and the real spec.
