What's the convention for referring to selectors in messages?

Question: What's the convention for referring a selector?

 Object>>selector 
or
 Object>>#selector

Actually, the convention is to use
"Object>>selector"
without the hash mark. This can be verified by selecting ">>" and pressing Ctrl-E.
[You will see lots of messages formatted this way.]


In 1999 some guy [BF?] decided it would be neat if this was valid Smalltalk and added
#>>
to class Behavior as a shortcut for
#compiledMethodAt:
.

Of course, this requires you to use a Symbol as parameter, hence the #. So you can actually do a print-it on
"Morph>>#delete"
in a workspace and the CompiledMethod for that method is returned.

[That's because]
#delete
can be passed (a symbol), and
delete
cannot.
So Yes,
"Morph>>#delete"
is a valid Smalltalk expression and
"Morph>>delete"
is not.
