The Proc
is the procedure object, which is the
encapsulated iterator block with context, such as local variables or
stack frames. The Proc
object acts like an unnamed
function except it does not have its own local variable
scope. (Although, dynamic local variables can have distinct value for
each Proc
.) The non local jump such as
return
, break
, next
,
redo
, retry
raise the exceptions, once
returned from Proc
creation methods.
Object
new
Wraps the iterator block with context and creates a new procedure object.
call(arg[,...])
Executes the procedure wrapped in the object. Arguments to the
call
are assigned to the iterator variables.
