[R6RS] Procedure call w/ non-procedure

[Michael Sperber]

Do we say anything about procedure calls where the first subform does
evaluate to something that's not a procedure?  I'm thinking a
&contract exception should be raised by analogy to invalid arguments.
I know that, say, MzScheme allows calling some records, but that's
covered by our allowing `procedure?' to return #t for records.
