fix(check): 0.R4 - a misspelled type in a parameter, a result or a field is refused where it is written

`function kind_of(f: CharFact)` for a CharacterFact was taken on trust and failed in the code writer
as "member access on non-aggregate". A capitalised type - plain, in a slice, or a generic's argument -
must name a declared property, record, state, event, enum, action or packed value type, or a type
parameter of its declaration: `kind_of's parameter f: there is no type CharFact`.
