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.
