Looking at the update patch...

It seems like all we need to get the original statement are the arguments 
passed to {{StatementSource.create()}}. (i.e. the start/end tokens and the 
token stream) What if we just held those in the {{StatementSource}} until we 
needed them in {{describe()}}, which I see is now being called lazily. In that 
case, can't we avoid materializing those strings until we actually have to 
report an error?

> does not return precisely the query user entered so the whole error message
