<sexpbot> ⟹ "Macro ([pred expr & clauses]); Takes a binary predicate,
an expression, and a set of clauses. Each clause can take the form of
either: test-expr result-expr test-expr :>> result-fn Note :>> is an
ordinary keyword. For each clause, (pred test-expr expr) is evaluated.
If it returns logical true, the clause is a match. If a binary clause
matches, the result-expr is returned, if a ternary clause matches, its
result-fn, which must be a unary function, is called with the result
of the predicate as its argument, the result of that call being the
return value of condp. A single default expression can follow the
clauses, and its value will be returned if no clause matches. If no
default expression is provided and no clause matches, an
IllegalArgumentException is thrown."
