Metadata for records and functions #88

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago

Jay has asked for two kinds of metadata on Orc values, to create some programs: 
iteration over entries of records, and arity of functions.

I propose to add two library sites, Keys and Arity. 

Keys(r) returns a list of all keys in the record r; the list may be empty if r 
is empty. If r is not a record, Keys(r) halts.

Arity(f) returns the integer arity of the function f. f must be a closure 
created by Orc. If f is not a closure, Arity(f) halts.
