It could have been defined that way.  I would have voted for adverb; it would certainly make the implementation easier.  But it wasn't.  You can write (1 2 o. y) to get sin & cos.

(;.3) is, in fact, an adverb, because ;. is a conjunction.

Hey,

Should the circle function o. not be internally defined as an adverb similarly 
to b.? Both do use their left argument only to define the action of the verb. 
Should a similar argument be made about the conjuction cut ;. and its n, which 
has only 8 possible values? What are the good reasons behind these decisions?
