The Proc
is the procedure object, which is the
encapsulated block with context, such as local variables and stack
frames. The Proc
object acts like an unnamed function
except it does not have its own local variable scope. (Although, local
variables which appear first in the block 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 block with context and creates a new procedure object.
self[arg...]
call(arg...)
Executes the procedure wrapped in the object. Arguments to the
call
are assigned to the block parameter.
