Is the punch line that CL will work for John'= Bateman's need?
Are there any qualifications?    (01)

Typed languages are included in the category of "segregated" CL
dialects, i.e., dialects that nontrivially partition the category of
names, notably into individuals constants and n-place predicate/function
symbols.  Additional typing restrictions on the permissible arguments
for a given predicate symbol or function symbol are allowed.  The spec
only requires that there be a category of atomic sentences in a dialect;
it does not legislate exactly which combinations of predicate and
argument sequence are to be deemed legitimate.    (07)
