Expr[1+6 div 6] doesn't entail a call to fn:subsequence, so how is it
relevant to STA of fn:subsequence?

And I don't understand why static typing implementations would have to be
'extended'. It seems to me that going from having to ask
    "Is the 2nd arg a 1 or $fs:last?"
    "Is the 2nd arg an expr?" (Duh!)
is a simplification, not an extension.
