HaloO,
I don't know if this is usefull and if it is were this information
should be put. I've reworked the Code class chart from A06 to look
as follows:
invocant(s) : Code
_________ ____:__ ___|___
| | : | |
SubMethod Method : Sub Block
___| : |___
| | : | |
Rule | : | Macro
|____:__|
| :
MultiMethod :
role Code {...}
role Return {...}
role Dispatch[ ::How ] {...}
class Block does Code
class Sub does Code & Return
{...}
class SubMethod does Code & Return & Dispatch of Class
{...}
class Method does Code & Return & Dispatch of Object
{...}
class Macro is Sub
{...}
class Rule is Method
{...}
class MultiMethod is Method & Sub does Dispatch of List
of Object
{...}
The vertical line of colons divides the methods from the subs basically.
This mirrors the declaration syntax of the invocants which are left of
the colon in a signature. The three underscore variables $_, @_ and %_
are right of the colon in my understanding and this is the main reason
for this mail: aliasing $_ in methods to the first invocant would badly
mix these two concepts!
Comments?
