Generic Function Lookup (7 methods)

( lookup collection key )

Part of:

package fset
If collection is a map, returns the value to which key is mapped.
If collection is a seq, takes key as an index and returns the
corresponding member (0-origin, of course). If collection is a set or
bag that contains a member equal to key, returns true and the member
as two values, else false and nil; this is useful for canonicalization.
