argument: % -> List S

argument(op(a1, ..., an)) returns [a1, ..., an].

from ConvertibleTo Pattern Integer

height: % -> NonNegativeInteger

height(k) returns the nesting level of k.

is?: (%, BasicOperator) -> Boolean

is?(op(a1, ..., an), f) tests if op = f.

is?: (%, Symbol) -> Boolean

is?(op(a1, ..., an), s) tests if the name of op is s.

kernel: (BasicOperator, List S, NonNegativeInteger) -> %

kernel(op, [a1, ..., an], m) returns the kernel op(a1, ..., an) of nesting level m. Error: if op is k-ary for some k not equal to n.

kernel: Symbol -> %

kernel(x) returns x viewed as a kernel.

name: % -> Symbol

name(op(a1, ..., an)) returns the name of op.

operator: % -> BasicOperator

operator(op(a1, ..., an)) returns the operator op.

smaller?: (%, %) -> Boolean

from Comparable

symbolIfCan: % -> Union(Symbol, failed)

symbolIfCan(k) returns k viewed as a symbol if k is a symbol, and “failed” otherwise.
